Rating of the best voltage regulators in 2020: price review, reviews

The further, the more stringent requirements for the quality of the electricity received, even ordinary household appliances, let alone fine electronics or professional systems lighting. To protect equipment from voltage surges in the network, voltage stabilizers are used. How to choose them and what 10 voltage stabilizers deserve the title of the best, we will now tell you.

Choosing a voltage regulator: what to look for

A type. On the market you can find several types of voltage stabilizers, which differ in the principle of operation, technical parameters and price:

• relay - the most affordable and therefore the most popular, of the pluses, a wide range can be noted operating voltages and a high stabilization rate, of the minuses - the low accuracy of the output voltage;
• electromechanical - more expensive, but much more accurate than relay ones, they are distinguished by a low stabilization rate and a narrow operating range;
• hybrid (combined) - combine an electromechanical basis, which gives a high the accuracy of work, and the relay part, which allows you to seriously expand the range of operating voltages by entrance;
• electrodynamic - expensive devices with very high stabilization accuracy and exceptional reliability, modified electromechanical stabilizers;
• electronic - accurate and fast devices with a wide range of input voltages, but one of the most expensive on the market;
• inverter - the most modern type of stabilizers with the widest operating voltage range, almost instantaneous response and low error, but the price usually bites.

Phase. If you don't know what this is, you probably need a single phase regulator. Three-phase are usually used to power private houses with specific wiring, industrial equipment and other consumers with a voltage of 380 volts.

Power. Lack of power can damage the gimbal. This parameter should be 20-30% higher than the total power consumption of all electrical appliances in the house. When calculating, take into account the fact that reactive consumers (for example, compressors, electric meat grinders and other devices with electric motors) have a starting current that is several times higher than the operating one. In addition, for reactive consumers, it is worth considering not only the active power (W), but also the total power consumption (VA), which is calculated dividing the power consumption by a special coefficient - it is usually indicated in the passport of the device, but for simplicity of calculation it can be taken equal to 0.7 or 0.8.

Stabilization accuracy. The higher the accuracy, the lower the error in the output voltage. It usually ranges from 2 to 8%.

Stabilization speed. Voltage equalizers do not work instantly, and this can affect the work of consumers, so the higher the speed, the better.

Working and limiting voltage range. These parameters indicate how high and how low the voltage the regulator can bring to normal. The working range is always narrower than the limit, since long-term operation of the device is possible in it. When operating at the limit of its capabilities, the stabilizer breaks down faster.

Indication. The simplest models are usually equipped with LED indication of operation, however today even inexpensive regulators usually have LCD displays that indicate the input and output voltage.

Installation. Depending on the weight, size and other design features, voltage stabilizers are installed on the floor or are hung on the wall, and among industrial models there are devices designed for installation in standard 19-inch racks.

FAQ

Why does the voltage regulator constantly click on and off?
Most likely, the point is not in the malfunction of the stabilizer, but in the fact that the voltage drops in the network go beyond its working (or even maximum) range. Compare the voltage at the input of the regulator with its nameplate range. If the first is seriously different from the second, then you need to think about replacing the stabilizer with a model with a wider range of operating voltages.
