Description

A microprocessor controls the power switches without mechanics, so the unit has no brushes or motor that would have to be replaced over time. The output voltage is held at 230 V ±4 %, which is enough for electronics, compressors and medical devices. The range from 20 to 400 A covers a single-phase input of almost any size, from an apartment to a small workshop with machine tools. The 115 V version is needed for networks and equipment with that rating. The smaller models have a vertical case, and the large ones are built in a floor-standing cabinet on wheels.

How to choose

The rated current of the stabilizer is chosen to be not less than the current of the main breaker, so that it does not become a bottleneck. For a residential house the lower part of the range is usually enough, and for a base station or workshop the larger models up to 96 kVA are needed. If the input is three-phase, AVR3x of 18–190 kVA with a separate regulator for each phase is better. For small loads and a wide input from 110 V, SVS…-22E of 1–10 kVA is suitable.

FAQ

What is the maximum power of the single-phase AVR stabilizer?

The larger models are rated for 400 A and a load of up to 96 kVA.

Is there an AVR stabilizer for 115 V?

Yes, the stabilizer is made for 230 V or 115 V networks, and the output accuracy in the 230 V version is ±4 %.

Does the AVR static stabilizer need maintenance?

There are no moving parts, so there will be no replacement of brushes or a motor, as in servo-driven models; it is enough to clean the ventilation periodically.

How do I choose the AVR stabilizer current for a house?

The stabilizer current must be not less than the rating of the main breaker, and the range starts at 20 A.

Is AVR of 20–400 A suitable for a base station?

Yes, among the applications the manufacturer names base stations, medical equipment, houses, workshops and offices.
