Voltage stabilizers for home: reviews. Which is better to choose a device for the protection of electrical engineering

Voltage stabilizers are devices that automatically regulate the voltage supplied to the network within the allowable value for trouble-free operation of electrical engineering. They can be used both for individual equipment (local), and used to protect the entire network as a whole (fixed).

The choice of stabilizer for the house begins with determining the type of power supply. In most cases, this is a single-phase power supply, when a cable with three or less wires is connected to the house. With this type of power used single-phase voltage regulators for the home. If the cable contains four conductors, the power is three-phase, designed for the operation of electrical equipment at a voltage of 380V. In this case, use three-phase voltage regulators for the home.

From the reviews it is known that in the case of three-phase power supply, if three-phase consumers are not supposed to work, three single-phase rectifiers can be installed, and they can be selected with different power and characteristics, which will also affect the total cost of the devices. So, for a separate low-power equipment, a local rectifier of insignificant power is selected, the cost of which is much lower than the more powerful analogs. In addition, a phase that is rarely used can generally be left unprotected. You can also use a more accurate equalizer on one phase, and a less accurate one on the other, and therefore a lower price.

Determining the required power for the equalizer, you can go two ways. In the first case, you should be guided by the automatic switch. If the machine limits the power supply to 25A, then the required stabilizer power is defined as the product of 25A x 220V = 5.5 kW. Adding the power reserve, we get the required stabilizer power of 6 kW.

Studying the opinions of users, you can find out what to reduce the power of the rectifier, and hence the cost of its acquisition, perhaps by summing up the power of all equipment. Taking into account that all equipment will not be switched on at the same time, you can opt for a less powerful device.

Another important indicator is the input voltage range.

Helpful advice! The operating voltage range at the input is considered to be the device range in which the rectifier not only works, but also ensures the stated accuracy of stabilization.

From customer reviews:

“Some incompetent sellers confuse the concept of a working range with a limit range in which the stabilizer will simply work without providing the stated accuracy of stabilization. Don’t fall for such tricks. ”

Stopping your choice on alignment accuracy, you should know that this characteristic shows how good the output voltage will be. Good feedback was received by Resant electromechanical stabilizers, which give an output voltage of +/- 2%. This indicator makes it possible to use these stabilizers for high-precision equipment and technology with electric motors.

The accuracy of regulating the stabilizer below 220V ± 3% with decreasing voltage affects lighting lamps and halogen lamps. It becomes noticeable to the eye to change the level of illumination when switching stages of the rectifier. Choosing a stabilizer, you should consider this factor.

For modern household equipment, it is necessary to select models with a stabilization accuracy of 220V ± 7%.

The presence in the house of audio equipment, hi-fi devices, expensive TV models, gas heating boilers with electronic control provides for a stabilizer with a high maintenance of voltage accuracy at the output – 220V ± 1%.

When deciding on which voltage regulator is better for a home, you should consider the main criteria:

  • protective factors – for rectifiers an important condition is the presence of protective functions that protect the device from short circuits, overheating and overloads that affect the correct operation and durability of the device;
  • voltage regulation at the input – it is worth choosing stabilizers with a control range of 210-230V. This model will allow connecting to the existing network equipment designed for Western standards without deteriorating the technical condition of the latter, as well as extend the life of incandescent lamps at 210V;
  • Automatic rectifier switching on – such a device is capable after shutdown (in the event of voltage over the limits of the operating range) after a selected period, the load is automatically resumed (in the event of a voltage return to normal). This will allow not to turn on the device manually;
  • matching the power at any voltage at the input – such a device is able to hold the declared power at the output when the voltage at the input is lowered.

Helpful advice! When purchasing a stabilizer, you should take into account that the device’s rated power will be much lower if the input voltage is lower than 220V. Strong voltage deviations can reduce the power of the device by half.

By visiting the thematic forums, you can learn from the reviews which voltage regulator is best for the house.

Here are some of them:

“With voltage fluctuations in the network up to 150V, it is better to purchase an Electromechanical Stabilizer ASN-15000/1-EM. This device, even at 140V input, provides 180V output. It works flawlessly, without breakdowns. And the sister of ASN-10000/1-C, electronic, does not even pull out the water pump. ”

“I bought Resant ASN-20000/1-EM three years ago, worked for several months and stopped leveling the voltage. He took it to the service center, under the warranty, they replaced the brushes. After repair works with high quality. “

Sergey Ushakov, St. Petersburg

“I have a Voltron PCH-3000 single-phase energy stabilizer installed, a device of compact dimensions, mounted on a wall and does not take up much space. Everything suits me. ”

When choosing a rectifier, you should pay attention to the ability of the device to transfer loads. For example, if a powerful 10kW device was purchased, and the mains voltage dropped to 160V, then the rectifier failed. Hence, the stabilizer was with a low load tolerance and at 160V had a power of 5 kW, instead of the stated 10 kW. Therefore, it is important what load the stabilizer can withstand when the voltage in the network changes.

Helpful advice! For normal operation of the rectifier, preference should be given to models with a high load capacity or to acquire a model twice as large in power from the planned design one.

The ability of rectifiers to withstand overload for some time is called overload capacity. This criterion shows the correctness and build quality of the device. Substandard models of transducers do not hold overload.

Reviews show that ORTEA devices, Italian voltage regulators for the house, the price of which is very high, have high-quality assembly, high resistance to overloads, normalization accuracy of ± 0.5, protective functions and electronic regulation.

From domestic manufacturers, Rectifiers are Calm, Leader. Reliable devices, however, the accuracy of stabilization of these models is ± 5.

Resanta company produces high-quality high-tech devices, focused on the requirements of international standards. They are distinguished by high accuracy of voltage at the output, excellent ability to withstand overloads, quiet operation and affordable price.

Reviews of Chinese manufacturers leave much to be desired. Such devices are usually of poor quality, sometimes they lack the function of normalizing voltage, they are short-lived and, accordingly, have a low cost.

When connecting a rectifier in the house, follow these rules:

  • if the equalizer is installed to protect the whole house, you should leave a branch for electrical appliances that can not be connected through a stabilizer;
  • the rectifier must have protection in the form of an automaton or a bypass jumper (bypass);
  • the device is connected only to the electric generator;
  • install stabilizer should be possible in a heated room.

Some users in the forums share information that, in the event of a breakdown of the device, it is possible to repair the household voltage regulator independently.

The current in the domestic electrical networks varies with high frequency, respectively, the servo actuator also often rotates, which can damage the motor of the device. Excessive friction and heating of the brushes contribute to their wear and clogging of the wires.

If the engine burned in the device, then you can go two ways. In the first case, purchase and install a new engine.

In the second case, it is possible to try to restore the engine with your own hands. First of all, it is necessary to disconnect the motor from the general circuit and connect it to a fairly powerful power source. If the outputs of the stabilizer supply current with a voltage of 5V and a current of 100 mA to 150 mA, then all the dust particles, stopping the work, will burn.

After that, a voltage regulator is connected using a simple scheme. After such a repair, the engine resumes operation.

From the reviews it is clear that many users purchase models of voltage regulators for a 10 kW house from Resanta. In this regard, the manufacturer offers a voltage regulator chip of 10 kW for consideration in the event of a possible failure of this type of rectifier. The schemes of the general structure of such rectifiers are similar, with the exception of some elements of devices with different power.

For the correct selection of a domestic stabilizer, use the recommendations of professionals and manufacturers, as well as consumer reviews on the compliance of the functions of the rectifiers with the declared characteristics.
