It warms up perfectly, it is tolerable.

On the downside, I would like to note that the consumption of diesel fuel is certainly too large, and does not at all coincide with the declared characteristics. And sometimes it starts to hum very loudly, although then this sound disappears, at first the people were even frightened, but this is tolerable. Overall not a bad model.

I ordered it to the workshop. It was all the same for the size, weight and design, the main thing was to warm up perfectly! I can say we were right. Warms what you need !!

I am engaged in auto repair. There is a huge box available. This unit is quite suitable for everything. It's warm in winter, in summer there is something to sit on.

Inverter welding machines are gaining more and more popularity among master welders due to their compact size, low weight and reasonable prices. Like any other equipment, these devices can fail due to improper operation or due to design flaws. In some cases, the repair of inverter welding machines can be carried out independently by examining the inverter device, but there are breakdowns that are eliminated only at the service center.

Welding inverters, depending on the models, operate both from a household electrical network (220 V) and from a three-phase (380 V). The only thing to consider when connecting the device to a household network is its power consumption. If it exceeds the capabilities of the wiring, then the unit will not work with a sagging network.

So, the following main modules are included in the device of an inverter welding machine.

Just like diodes, transistors are installed on radiators for better heat dissipation from them. To protect the transistor unit from voltage surges, an RC filter is installed in front of it.

Below is a diagram that clearly shows the principle of operation of the welding inverter.

So, the principle of operation of this module of the welding machine is as follows.The primary rectifier of the inverter is supplied with voltage from the household electrical network or from generators, gasoline or diesel. The incoming current is alternating, but passing through the diode block, becomes permanent... The rectified current is fed to the inverter, where it is converted back to alternating current, but with changed frequency characteristics, that is, it becomes high-frequency. Further, the high-frequency voltage is reduced by a transformer to 60-70 V with a simultaneous increase in the current strength. At the next stage, the current again enters the rectifier, where it is converted to DC, after which it is supplied to the output terminals of the unit. All current conversions controlled by a microprocessor control unit.

Modern inverters, especially those based on the IGBT module, are quite demanding on the rules of operation. This is explained by the fact that when the unit is operating, its internal modules give off a lot of heat... Although both radiators and a fan are used to remove heat from power units and electronic boards, these measures are sometimes not enough, especially in inexpensive units. Therefore, you need to strictly follow the rules that are indicated in the instructions for the device, implying periodic shutdown of the installation for cooling.

This rule is usually referred to as the “Duty Cycle” (Duty Cycle), which is measured as a percentage. Not observing the PV, overheating of the main units of the apparatus occurs and their failure occurs. If this happens with a new unit, then this breakdown is not subject to warranty repair.

Also, if the inverter welding machine is working in dusty rooms, dust settles on its radiators and interferes with normal heat transfer, which inevitably leads to overheating and breakdown of electrical components. If it is impossible to get rid of the presence of dust in the air, it is necessary to open the inverter case more often and clean all the components of the device from accumulated dirt.

But most often inverters fail when they work at low temperatures. Breakdowns occur due to the appearance of condensation on the heated control board, as a result of which a short circuit occurs between the parts of this electronic module.

A distinctive feature of inverters is the presence of an electronic control board, therefore, only a qualified specialist can diagnose and eliminate a malfunction in this unit.... In addition, diode bridges, transistor blocks, transformers and other parts of the electrical circuit of the apparatus can fail. To carry out diagnostics with your own hands, you need to have certain knowledge and skills in working with measuring instruments such as an oscilloscope and a multimeter.

From the above, it becomes clear that, without the necessary skills and knowledge, it is not recommended to start repairing the device, especially electronics. Otherwise, it can be completely disabled, and repairing the welding inverter will cost half the cost of a new unit.

As already mentioned, inverters fail due to external factors affecting the “vital” units of the apparatus. Also, malfunctions of the welding inverter can occur due to improper operation of the equipment or errors in its settings. The most common malfunctions or interruptions in inverter operation are as follows.

Very often, this breakdown is caused by faulty network cable apparatus. Therefore, first you need to remove the cover from the unit and ring each wire of the cable with a tester. But if everything is in order with the cable, then more serious diagnostics of the inverter will be required. Perhaps the problem lies in the standby power source of the device. The repair technique for the “duty room” using the example of a Resant brand inverter is shown in this video.

This malfunction can be caused by an incorrect setting of the amperage for a certain diameter of the electrode.

You should also consider and welding speed... The smaller it is, the lower the current value must be set on the control panel of the unit. In addition, to match the current strength to the diameter of the additive, you can use the table below.

If the welding current is not regulated, the cause may be breakdown of the regulator or violation of the contacts of the wires connected to it. It is necessary to remove the cover of the unit and check the reliability of the connection of the conductors, and, if necessary, ring the regulator with a multimeter. If everything is in order with him, then this breakdown can be caused by a short circuit in the inductor or a malfunction of the secondary transformer, which will need to be checked with a multimeter. If a malfunction is found in these modules, they must be replaced or rewound to a specialist.

Excessive power consumption, even when the device is not loaded, most often causes turn-to-turn closure in one of the transformers. In this case, you will not be able to repair them yourself. It is necessary to take the transformer to the master for rewinding.

This happens if the voltage drops in the network... To get rid of the sticking of the electrode to the parts to be welded, you will need to correctly select and set up the welding mode (according to the instructions for the device). Also, the voltage in the network may sag if the device is connected to an extension cord with a small wire cross-section (less than 2.5 mm 2).

It is not uncommon for a voltage drop that causes the electrode to stick when using a power strip that is too long. In this case, the problem is solved by connecting the inverter to the generator.

If the indicator is on, this indicates overheating of the main modules of the unit. Also, the device can turn off spontaneously, which indicates tripping of thermal protection... So that these interruptions in the operation of the unit do not occur in the future, again, it is necessary to adhere to the correct mode of the duration of the on (DC). For example, if duty cycle = 70%, then the device should work in the following mode: after 7 minutes of operation, the unit will have 3 minutes to cool down.

In fact, there can be a lot of various breakdowns and the reasons that cause them, and it is difficult to list them all. Therefore, it is better to immediately understand what algorithm is used to diagnose the welding inverter in search of faults. You can find out how the device is diagnosed by watching the following training video.

Resanta voltage stabilizers can be found in many apartments in our country, which is understandable. This is due to the fact that such units make it possible to normalize the operation of all electrical appliances that are present at home. In other words, they allow you to save quite expensive equipment in the event of an overload in the network, or in case of voltage surges, thereby significantly extending the operational life of all electrical equipment.

However, the operation of the voltage stabilizer also carries the risk of certain breakdowns, the only way out of which is timely repair.

There may be several reasons for this - from improper operation to natural causes of breakdown, i.e. long service life.

To avoid this, you must exactly follow the instructions that are included in the kit, which allows you to significantly extend the service life of the unit in the correct mode of operation. If, nevertheless, a breakdown did happen, then you need to know what methods you need to correctly carry out repairs with your own hands, so as not to further aggravate the situation. In this article, we will look at the main malfunctions, as well as ways to eliminate them in a timely manner.

This video shows the Resant's stabilizer with a malfunction

The constructive structure of the Resant voltage stabilizer is as follows:

automatic transformer;
the electronic unit;
voltmeter;
a control that is responsible for starting and disconnecting some windings.

This manufacturer produces many different types of stabilizers, therefore, these winding connection organs will differ. We will talk about all these nuances a little later, during the consideration of the repair procedure.

In this design, the decisive factor is the electronic unit, which carries out the general control of the entire system of the unit. He is responsible for the operation of the voltmeter, and also receives information about the power of the input voltage. Then, the block compares the obtained values with the optimal ones, determining the next action, i.e. whether you need to add a few volts or, on the contrary, subtract a certain amount.

Further, along the chain, there is a determination of the necessary windings - which of them need to be started and which ones to be disabled. Then, the electronic unit performs one of these actions, after which all electrical appliances in the apartment receive a stable current.

Of course, the stabilization process itself can be slightly different, depending on the type of device produced.

This difference applies to the types of windings, as well as the methods of starting and disconnecting them. Today, the Resanta company produces two types of these stabilizers:

Electromechanical type.
Relay.

Accordingly, their repair will be somewhat different.

Let's start our consideration with stabilizers of the electromechanical type. In its design there is a servo drive, which starts and turns off the windings in the device.

The servo itself consists of a motor on which an electrical contact (brush) is located. When the armature of this motor moves, accordingly, this brush also rotates, constantly contacting with copper windings. The width of this brush allows for a complete wrap-around of the entire winding, which allows the phase not to be lost.

In order for the brush to move in a given direction with the desired characteristics, an error voltage arises in the device. Then, this voltage value rises. Then it is transmitted to the engine, which makes the armature rotate in the optimal direction. Accordingly, the brush also moves, like the armature, in the same predetermined direction. In this case, direct contact with the windings is carried out.

The error voltage value will be proportional to the value formed by the difference between the real voltage value at the input and the value that should be there. This signal can have one of two polarities, each of which specifies a certain direction of movement. Below is a diagram of a similar voltage regulator:

Regardless of the specific model, the structure of this voltage regulator will be almost the same. They differ among themselves by different power values and individual circuit elements.

All relay stabilizers equalize the current values by surges. This is because the relay starts or turns off the turns located on the second winding. An electromechanical stabilizer performs this process more smoothly than a relay one.

Relay units from Resant connect the turns until they find the right one. All these turns are conventionally divided into subgroups, and from each turn there is an output to which the current flows when the device is started.

The diagram of all relay stabilizers of this brand shows that there are about four relay elements in its design. In some cases, this number can be equal to five (SPN models).

In the case of relay stabilizers, it is the relay that is the most vulnerable point of the entire device. This is due to the fact that it is in a constant operating mode, which significantly increases the risk of failure.

Having considered the principles of operation of both types of voltage stabilizers, we can conclude that it is their main components that are the most frequently breaking system components. We are talking about a servo drive in electromechanical devices, as well as relays in relay ones.

In the first case, the constant movement of the servo leads to periodic friction of the turns of the coil and brush, which leads to excessive overheating of these components. It also causes severe wear and tear and sparks from copper wires.

It is also necessary to bear in mind the fact that the current value periodically changes in the network, which provokes a similar change in the movement of the servo. Such unstable operation can lead to the failure of this device.

Repair of one of the faults is demonstrated in the video.

The repair of the Resant's stabilizer can be roughly divided by the type of breakdown.First, consider the situation when the Resant servo motor has failed. There are two ways out of this problem.:

Buy a new motor, then install it in the device.

Try to repair the damaged one.

While everything is clear with the first case, the second requires detailed consideration. It is important to understand that in case of successful repair work, the restored engine will not be able to work for a long time, i.e. this is a temporary measure.Everything our actions will boil down to the following:

Disconnect the servo motor from the general structure. Then we connect it to a power source with sufficient power.

It is necessary to supply a current of 5 V to the outputs of the motor. The indicator of the current strength must be at least 90 mA.

The implementation of these manipulations will normalize the operation of the stabilizer. Next, you need to connect the motor back to the circuit.

The circuit is quite simple: the input cable is connected to the input terminal, the neutral cable is connected to the neutral terminal. The same manipulations are performed for the output cables. Also, remember to connect the ground wire.Failure of the relay is often leads to breakage of transistors... For example, in the ASN-5000 model, there are D882P transistors. The diagram is shown below: Image - Resanta tdp 20,000 DIY repair

If these transistors fail, then you need to purchase new ones in their place. You can buy them quite freely, because many specialized stores sell equipment and components of the Resanta brand.

You can also try to repair damaged parts:

First you need to remove the relay cover. Next, we remove the movable contact, freeing it from the spring.
Using sandpaper, we clean off all carbon deposits from the contact. We carry out this manipulation for both contacts - upper and lower.
Then we lubricate the contacts with gasoline, after which we assemble the relay structure.

Another possible problem is the disordered switching on of the display, as well as the switching on of the relay itself. The reason for this may be the XTA1 resonator, which may have an incorrect soldering.

The repair is as follows:

We solder this resonator with a soldering iron.
We clean the leads with sandpaper.
We solder the resonator back.

Specialist's story about Resant's repair

To make diagnostics, we need a LATR device, i.e. laboratory autotransformer of controlled type. We connect the stabilizer to this device, with which you need to change the voltage values. In parallel, we are monitoring the work of the Resant stabilizer.The implementation of repair work, in this case, can be done at home. At the same time, it is assumed that the person performing these manipulations will be well acquainted with such a technique, have the skills of proper soldering and some knowledge in electronics. If a person does not possess this, then it would be more expedient to contact specialists.There are quite a few similar service centers in Moscow and St. Petersburg. In particular, "Demal-Service", located at the address: Moscow, st. 1st Vladimirskaya, house 41.In St. Petersburg there is a service center of the company itself, located at the address: st. Chernyakovsky, house 15. Image - Resanta tdp 20,000 DIY repair

The way of operation of the Resanta sai 250 welding machine and its circuit do not differ from similar devices of other manufacturers. The incoming AC current of a conventional 220 V power grid is converted first to direct current, with a value of 400 V, which is then changed to a modulated high-frequency voltage. After that, a step-down transformer is turned on, which reduces the converted current to a working state.

The principle of operation of the inverter is based on converting an alternating current of 50 Hertz from a conventional household power supply into a direct current. This voltage indicator has a magnitude of 400 volts... The current of the welding machine is regulated by modulation (by and large, it is a wide-pulse) of the obtained high-frequency voltage.

The considered device for welding Resant SAI is made in a steel case. On the outer part of this body there are power connectors for connecting welding cables, two indicators ("Mains" and "Overheating"), a regulator for selecting the characteristics of the welding current. Also in the case there is a special hole through which hot air is removed from the device. It is part of a forced ventilation system that protects the inverter from extreme overheating during operation.

The Resant Sai inverter also has one more protection system, it automatically turns off the device in cases where power cords are short-circuited. Moreover, the corresponding indicator on the front control panel starts blinking. The inverter is distinguished by the presence of several important functions that are often used during operation:

Hot start guarantees fast and high-quality ignition of the welding arc due to an increase in the level of the welding current (the worker does not need to do anything, the current increases in automatic mode). And the anti-stick mode, on the contrary, reduces the welding current if, during the ignition of the arc, adhesion of the welding wire (electrode) is noted. Then, when the adhesion is removed, the welder automatically restores the welding performance on its own.

The main advantage of this welding inverter for household needs of consumers is that it is specially adapted for connection in those power grids in which low voltage of the mains (130-250 Volts)... Resant SAI works without interruptions at the specified voltage when welding in manual arc mode.

You can use rods for welding up to 6.0 mm. The welding current in the device can be adjusted up to 250A. It is also important that the device is able to withstand rather heavy workloads for a long time. This property positively distinguishes its scheme of work from other devices, which are found in abundance on the windows of specialized hardware stores.

Idling Resanta SAI's welding device operates with a voltage of 80 Volts. The durability of the device at a fairly high power is ensured in its circuit by the design of modern high-quality IGBT transistors.In addition, this welding inverter has a high degree of protection - IP 21 protection level.

One cannot fail to mention the compactness of this welding machine, as well as its excellent mobility. Equipped with a handle for carrying the device, it makes it easier to carry it around the territory of the site where the construction is taking place. Also, consumers note the accuracy and simplicity of setting up the Resant sai welding inverter. At the same time, the specified indicators are guaranteed to retain the established data even in cases where the electrical network does not differ in the stability of its voltage indicators.

Specifications of the Resant SAI apparatus of interest to us are as follows:

maximum current consumption - 35 Amperes;
load duration at 250 Amperes - not less than 70%;
welding adjustment interval - 10-250 Amperes;
working temperature range of the environment - -10 / + 40C;
arc voltage - 30 Volts.

If necessary, this device can be connected to the equipment of a generator that runs on gasoline. It is best to choose a generator with a power of more than five kilowatts.

Attention! When choosing a welding electrode (the electrode can be no more than 6 millimeters in diameter), it must also be taken into account that the welding current decreases when the input current decreases.

The scheme for preparing the welding device for operation is quite simple, but it must be performed as accurately as possible if you want the device to serve you for a long time and without repair. First of all, you need to connect the cord with the electric holder and the ground wire to the power terminals of the machine (you must definitely pay attention to the polarity of the welding rod that you are using).

Put the regulator for minimum welding current, then you can connect the inverter to the power grid, and then turn it on. The required level of welding current must be selected based on the indicators recommended by the manufacturer of Resant SAI:

200-300 Amperes - electrode diameter 6 millimeters;
160-200 Amperes - 5 millimeters;
130-160 Amperes - 4 millimeters;
90-140 Amperes - 3.2 millimeters;
60-90 Amperes - 2.5 millimeters;
50-60 Amperes - 2 millimeters;
25-50 Amperes - 1.6 millimeters.

After welding, the current is set to the minimum value by means of the regulator, the inverter is turned off (first by a switch, and then from the mains). You also need to disconnect the electrical holder and grounding cord from the device.

Before switching on, the device must be kept at a positive air temperature for several hours. Otherwise, condensation may form in it, which may damage the inverter. It is strictly forbidden to operate the device in cases where its welding cords or the wire connecting to the mains are deformed (even slight).

Near a switched on welding machine, you cannot process metal and steel parts using grinders, electric jigsaws and similar equipment, during which metal dust appears... Dust can enter the cabinet and damage the inverter. In addition, it is forbidden to operate the unit in open areas in the rain or in rooms with high humidity.

Before operating the Resant SAI inverter, it is imperative to study the "Safety Rules for Users of Electrical Devices" and "Rules for the Operation of Household Electrical Installations". During operation welding machine you need:

create access to fresh air in the room where welding is carried out (when welding takes place indoors, then it must be well ventilated);
work in a welding protective mask, gloves, a headdress and special clothing that protects the body from possible thermal burns;
comply with fire safety rules.

It is necessary to store the welding device in rooms where the formation of acidic or alkaline vapors is excluded, and there is no excessive dustiness.Optimum characteristics for storing the device:

temperature - not higher than +55 and not lower than -15 degrees;
relative humidity - no more than 70 percent.

The operating reserve and potential of this inverter is quite high. The device is classified by many foreign experts as one of the best in its group. When used correctly, this equipment repairs may not be required for years (even if the inverter is used quite actively). But, of course, there is no eternal equipment, so you need to be prepared for the fact that the welding device will probably need to be repaired.

It is best to do the repairs by the craftsmen (in many localities there are authorized centers that deal with the equipment of the "Resanta" company). Moreover, the user can fix some minor breakdowns with his own hands. For example, when on the control panel overheating indication appears, then you need to clean the device from dust accumulated in it.

But, if the welding machine cannot reach maximum power, then drying the electrode, which is used for welding, can help. It is often the damp welding rod that causes poor equipment performance. The same problem appears in cases where the voltage in the electrical network is very weak.

This article will cover such questions:In many houses and apartments, voltage stabilizers are used that were made within the walls of the Resanta company. Through the use of these appliances, owners ensure stable performance and protect the "health" of all their household electrical appliances.Ultimately, every household appliance works for a long time and rarely needs repair. Image - Resanta tdp 20,000 DIY repair

We would like to note that the stabilizer is also a household appliance that requires proper care and adherence to the necessary operating conditions. Otherwise, the voltage stabilizer produced by the "Resanta" company may fail and will need to be repaired.

In addition, it can fail after many years of operation. In other words, it also has the ability to break.

Looking at this ability, we decided to devote an article to the weak points of Resanta stabilizers and consider how to repair damaged elements, as well as restore the full functionality of this popular device.

But, first, let's talk about the general structure and principle of operation of devices of this brand.

Like all voltage stabilizers and normalizers of the "Resanta" brand, they consist of:

automatic transformer.
electronic unit.
voltmeter.
an element that connects / disconnects certain windings.

Considering that the manufacturer produces various types of stabilizers, the elements for connecting the windings are different. We will note about them a little below, namely when we consider the features of the operation and repair of each type of normalizer from a Latvian manufacturer.

The electronic unit of any stabilizer of the company "Resanta" controls the entire operation of the device. It controls the operation of the voltmeter and receives information about the input voltage level. Then he compares this voltage with the normalized one and determines how many volts to add or subtract.

After that, it is determined which stabilizer windings need to be connected or disconnected. When this information is known, the electronic unit connects / disconnects the necessary windings using a relay or servo drive and our electrical appliances receive a normalized current.

This principle of current stabilization is inherent in each voltage stabilizer from the "Resanta" company. However, the stabilization process in various models of the company differs. They are due to the fact that the connection / disconnection of the transformer windings occurs in different ways.

Within the walls of the company, two types of stabilizers are produced:

And, of course, the repair of each of them has its own characteristics.

We will first look at an electromechanical normalizer. The device of this voltage stabilizer from the "Resanta" company provides for the presence of such an element as a servo drive. Actually, thanks to him, the switching of various windings of the automatic transformer is carried out.

The switching of these windings is smooth and the result is a precise control of the output voltage.

How does this smooth adjustment take place? A servo is a motor and a brush (electrical contact) that is attached to the armature of the motor. When this anchor turns, the brush also moves. She is constantly in contact with the copper windings of the transformer.

In fact, she slides over them. It is wide enough to connect two windings at the same time. As a result, there is no phase loss at the output.

In order for the brush to move in a certain direction and by a certain amount, an error voltage is created in the normalizer. Further, thanks to the operational amplifier and the transistor output stage (it is a power amplifier), this voltage is amplified.

After that, it is fed to the engine and makes the armature spin in a certain direction.

The brush moves in this direction, which is in contact with the windings. The error voltage is proportional to the difference between the number of volts at the input and the required number of volts.

The error signal can have one of two polarities, and as a result, each polarity causes the motor axis to rotate in a specific direction. These are the features of the operation of the electromechanical normalizer.

Note that many people buy a 10KV electromechanical regulator. Therefore, possible malfunctions and breakdowns of this type of voltage stabilizer from the "Resanta" company will be considered on this model. Below is its wiring diagram.

Rice. 1. Wiring diagram of the ASN-10000/1-EM stabilizer.

It is worth paying attention to the fact that the general structure of all normalizers of this type is similar. The differences lie in the individual elements of the models with different power levels.

From the above-described principle of operation of the electromechanical stabilizer, it becomes clear that when there is a change in the current in the mains, there is a simultaneous rotation of the motor armature and the movement of the graphite brush.

The constant movement of the servo is the main weakness of the electromechanical device. Why? Because as a result of the friction of the brush against the coil turns, excessive heating of both the brush and the turns under it occurs.

In addition, friction causes brush wear and contamination of the copper wires. The latter cause sparks.

Considering the fact that in our power lines the current changes very often, the servo drive moves with the same frequency. Such frequent rotation causes the failure of the engine itself.

A notable feature is that engine failure causes other parts to fail. So, there is a possibility of failure of the output stage of the engine control.

Resanta specialists assemble this stage based on a pair of transistors Q2 TIP41C and Q1 TIP42C. When these transistors burn out, the resistors R45 and R46 also burn out.

They are the components of the collector circuit of the above transistors. R45 and R46 are characterized by a resistance of 10 ohms and a power of 2 watts.

When there are such malfunctions, then it is necessary to check the linear stabilizer. Its Latvian specialists assemble on the basis of a DM4 zener diode and a Q3 TIP41C transistor.

If all these components of the electrical circuit of an electromechanical voltage stabilizer manufactured by Resanta have burned out, then in any case they need to be bought and replaced.

When the engine itself burns out, then there are two options:

Buying a new one and installing it.
An attempt to restore an old engine.

The second option makes it possible to reanimate the engine on its own, however, not for a long time. For resuscitation, it is necessary to disconnect the engine from the general circuit. After that, it must be connected to a powerful power source.

Your task is to supply current to its outputs with a constant voltage of 5 volts. In this case, the current must be between 90 and 160 mA. When such a current is applied, every small particle of "debris" burns out on the motor brushes.

Helpful hint: since the motor is of the reversible type, the polarity must be reversed when voltage is applied. This procedure is carried out two times.

After such actions, the engine will be able to work again, and the stabilizer will perform its main function. Further, according to a simple scheme, you can carry out the procedure for connecting a voltage stabilizer manufactured by Resanta.

This diagram involves connecting the input phase and neutral cables to the input phase and neutral terminals, respectively. The connection of the output wires is the same. Also, be sure to connect the ground wire.

As for the relay stabilizers from the Latvian company, other malfunctions occur during their operation. Accordingly, their repair is a different procedure.

Before considering the peculiarities of repairing the "Resant" relay normalizer, let us pay attention to the peculiarities of its operation. The relay device equalizes the current in a stepwise manner.

This is because one relay connects / disconnects a certain number of turns of the second winding. If we compare an electromechanical stabilizer, then its brush gradually comes into contact with a large number of turns.

In other words, it gradually connects the intermediate turns and stops at the desired turn. In relay devices from "Resant" all the loops are divided into groups and the output goes from each of them. Actually, current is supplied to this output when the relay is turned on.

The electrical circuit of each relay voltage stabilizer from the "Resanta" company provides for the presence of four relays, which means that the number of terminals of the second winding is also four.

The exception is the models of the SPN series. The number of relays is five.

Helpful advice: when a certain relay turns on or off, the output voltage changes by 15-20 volts, that is, there are mini voltage surges. These mini jumps are clearly visible on the lights.

For most electrical appliances, they are not scary. However, sophisticated electronic and measuring technology requires a smoother current stabilization. This should be taken into account when using any relay stabilizer.

Summarizing the above, we note that the entire process of current normalization is accompanied by the constant operation of the relay. Actually, this mechanical component is the weakest point. During operation, it can both burn out and stick.

In the event that the relay contacts fail, transistor keys can also break. Depending on the model, these keys can be collected on different transistors. So, in the SPN-9000 model, these keys are assembled on the basis of 2SD882 transistors.

At the heart of the transistor switches of the ASN-5000/1-Ts model (its diagram is given below) are the D882P transistors. All of these transistors are manufactured by NEC.

In cases where these transistors and relays fail, they are completely replaced. Such spare parts for the aforementioned models of voltage stabilizers manufactured by Resanta can be found in many stores.

You can also try to restore worn relay contacts. This procedure begins by removing the relay cover. Then they begin to remove the movable contact. This contact must be released from the spring.

Next, they take "zero" sandpaper and clean this contact from all burnt particles. The same cleaning procedure must be done with respect to the upper and lower contacts.

At the end, all contacts are processed with Galosha gasoline and the relay is assembled.When the relay is assembled, you should check the 2SD882 or D882P transistors, or others (this depends on the modification).

They are soldered (you need to have a soldering iron) and the integrity of the transitions is checked. If the junctions are not holistic, you need to take new transistors.

After

After the completion of the repair work, it is necessary to diagnose the operation of the stabilization device. To do this, use LATR, to which the stabilizer is connected. Then, with the help of LATR, the voltage is changed and the operation of the stabilization device is monitored. A light bulb is used as a load.

After verification, you can connect to the public network. If you do not know how to connect a relay voltage stabilizer made within the walls of the "Resanta" company, then it is worth remembering that this procedure is the same as for an electromechanical normalizer. We have already written about it.

JAKEC capacitor set

It is worth noting that a breakdown of a relay may not be the only malfunction that occurs in a relay normalizer from a Latvian company. In some cases, a periodic defect was observed in the SPN-9000 stabilizer.

An external sign of this defect was a chaotic display of display segments that were turned on. At the same time, a chaotic switching on of the relay was observed.

The reason for this lies in the cold soldering of the XTA1 quartz resonator, which has an operating frequency of 8 megahertz. This soldering causes the microcontroller U2 to malfunction.

To solve the problem, you need to evaporate this resonator, clean its terminals with zero sandpaper, carry out a high-quality soldering and put it back.

Experts also recommend checking the electrolytic capacitors located on the controller board. This must be done for the reason that the company uses capacitors from the manufacturer JAKEC. These capacitors are not of high quality. During their verification, capacitance and ESR measurements are carried out.
