18 best voltage stabilizers

Review of the best according to the editors. About the selection criteria. The the material is subjective, is not advertising and is not serves as a guide to the purchase. Before purchase is needed consultation with a specialist.

In each house or apartment you can count dozens electrical appliances. And if some of them are unpretentious to quality electricity, then others are afraid of strong voltage fluctuations. So that expensive refrigerators, computers or gas boilers do not out of order, homeowners acquire stabilizers voltage. However, not all models available in the distribution network are capable of solve the problem of unstable electricity. Today to the consumer different designs are offered, products differ in power and the price. When choosing the optimal device for the home, experts recommend paying attention to several parameters.

  1. A type. Structurally, stabilizers are relay type, electromechanical, hybrid, electronic. Each of them has its advantages and limitations. You should be aware of them so as not to give up on work.
  2. Before going to the store, it’s useful to know the peak values voltage in your single phase network. Usually a decrease to 90 … 140 V, but sometimes there are surges up to 270 V. Here in this input voltage range, the stabilizer must successfully work.
  3. Load. Be sure to calculate what load will test the stabilizer. To do this, summarize power of the refrigerator, TV, computer, gas boiler and other voltage-sensitive electrical equipment. It is desirable that the active power of the stabilizer exceed the resulting value is 20%. For example, for computer and TV 500-1000 watts of power will be enough.
  4. Efficiency. The voltage regulator consumes electrical energy, so efficiency will be an important indicator. The higher it is, the the device will work more efficiently and there will be less loss electricity.
  5. Accuracy. Often found by users electrical equipment demanding stability voltage. In this case, experts advise to pay attention to stabilization accuracy. This value indicates the error, s which voltage will come out of the stabilizer. Normative documents, this indicator is limited to 8%, but it is better to choose models with an accuracy below 5%.
  6. Noise. When connecting the stabilizer to a refrigerator or gas boiler means round-the-clock operation of the device. Quite often, silent operation comes first, especially when the device will be next to the nursery or bedroom.
  7. Although the stabilizer is considered a stationary device, but bulky and heavy products often deliver a lot to users hassle. If you can’t hide it behind the curtain, then will have to choose a model based on appearance.
