18 best voltage regulators

In each house or apartment you can count dozens of electrical appliances. And if some of them are unpretentious to the quality of electricity, others are afraid of strong voltage fluctuations. To costly refrigerators, computers or gas boilers do not fail, homeowners purchase voltage stabilizers. However, not all models available in the trading network are able to solve the problem of unstable electricity. Today, different designs are offered to the consumer, products differ in power and price. When selecting the optimal device for the home, experts recommend paying attention to several parameters.

1. Type of. Structurally, stabilizers are of relay type, electromechanical, hybrid, electronic. Each of them has its advantages and limitations. You should be aware of them in order not to be disappointed while working.
2. Before going to the store, it is useful to know the peak voltage values ​​in your single-phase network. Usually, a decrease to 90 ... 140 V is observed, but sometimes bursts up to 270 V. Occur in this range of input voltages, the stabilizer should work successfully.
3. Load. Be sure to calculate the load the stabilizer will experience. To do this, sum up the power of the refrigerator, TV, computer, gas boiler and other electrical equipment sensitive to voltage drops. It is desirable that the active power of the stabilizer exceeds the value obtained by 20%. For example, for a computer and a TV there will be enough device power of 500-1000 watts.
4. Efficiency. The voltage stabilizer consumes electrical energy, so efficiency will be an important indicator. The higher it is, the more efficient the device will be and the less electricity will be lost.
5. Accuracy. Often users find electrical equipment that is demanding for voltage stability. In this case, experts advise to pay attention to the accuracy of stabilization. This value indicates the error with which the voltage will go out of the stabilizer. Regulatory documents, this indicator is limited to 8%, but it is better to choose models with an accuracy of less than 5%.
6. Noise. When connecting the stabilizer to the refrigerator or gas boiler means round-the-clock operation of the device. Quite often silent work comes to the first place, especially when the device is near the nursery or the bedroom.
7. Although the stabilizer is considered a stationary device, but bulky and heavy products often cause users a lot of trouble. If you can’t hide it behind a curtain, then you will have to select a model based on your appearance.
