Three-phase voltage stabilizer - review and rating. Technical parameters, advantages, pros and cons of popular models. Selection criteria and features of three-phase voltage stabilizers.

A three-phase electrical network can be connected not only to industrial, but also commercial, social and even domestic facilities.

To compensate for voltage fluctuations and protection of connected devices appropriate stabilizers are used here.

In this review, we will consider the selection criteria and features of three-phase voltage stabilizers, analyze their technical parameters, find out the pros and cons of popular models.

What to look for when choosing?

Before buying a three-phase stabilizer, you should pay attention to the following key points:

Connection options.
Three-phase stabilizers are usually used to connect a similar load.
In some cases, they are acceptable for powering 220 V devices connected to a single phase.
Type of equipment.
Powerful three-phase stabilizers use an electromechanical or relay method to equalize the mains voltage.
More accurate inverter devices with double energy conversion are less common and cost an order of magnitude more expensive.
Rated power.
The value determines the total power consumed by the equipment connected to the stabilizer.
Taking into account the overloads that are typical for devices with electric motors or transformers, the stabilizer must have at least a 2-fold power reserve.
stabilization accuracy.
The lower this indicator, the better.
For household equipment and office equipment, an error of 5 percent is sufficient; for laboratory and television equipment, it is better to choose a stabilizer with an accuracy of no more than 1-2 percent.
Input voltage.
This is a fairly wide range from the minimum to the maximum value.
When the limit is exceeded, the stabilizer turns off the power to consumers or turns off by itself.
Additional options.
In modern stabilizers, the controls and controls are often not limited to the start button and the indicator light.
Digital displays, voltage regulators and even remote control via the Internet enhance the convenience and efficiency of the device.

Top models up to 10,000 W
