What are voltage surge and sag

Voltage spike and plunge is a voltage change of short duration, during which the voltage changes up to 10% to 90% of the rated value, and lasts from 0.5 periods to 1 minute

How YIY-AVC works

The YIY-AVC is an inverter based system that protects sensitive industrial and commercial loads from voltage disturbances.Providing fast, accurate voltage sag and surge correction as well as continuous voltage regulation and load voltage compensation.

The grid voltage is normal

The grid voltage sag

The grid voltage surge

The bypass mode

Excellent compensation effect

YIY-AVC can provide fast and accurate voltage protection to prevent the damage caused by voltage surge and plunge.

2ms

Response time is 2ms

±0.5%

Voltage output accuracy±0.5%

3 / 1

Three-phase/single-phase voltage compensation

load voltage

response time was 2.0 milliseconds

As can be seen from the waveform diagram, when the grid voltage changes, YIY-AVC can switch to the working state within 2 milliseconds, and there is no current surge in the switching process, and the compensation effect is smooth

Application scenarios

YIY-AVC, with its fast response and precise output accuracy, can provide perfect voltage protection for electronic numerical control equipment, it industry equipment, sensitive mechanical equipment and so on
