Voltage Regulator

AVR

Using high-performance IGBT technology, this UPS provides stable output power and precise frequency conversion for a wide range of industrial and testing applications.

Main Functions

APRO Electronics’ AVR maintains constant voltage using a stationary semiconductor device (triac).
It is an excellent system in that no spark voltage or impulse caused by power switching occurs.

In addition, a special control circuit employing a zero-crossing switching method is built in to completely protect both the load and the operator, preventing malfunctions.
This ensures maximum equipment performance as well as a high level of reliability.
