Product Description

Customized Auto Voltage Regulator 90KW 50Hz With CE / ISO Certificates


1. Quick Profile


AVR, with its full name of automatic voltage stabilizer, generate a fixed output voltage that remains constant regardless of changes to its input voltage or load condition. This product introduced here is a 90KW AVR voltage stabilizer, of which the input voltage can be 304V to 456V while the output voltage could be 380V or 400V or be customzied according to your needs.


The major components of this AVR are three carbon brushes,  three servo motors, three copper coils, three compensating coils, three circuit boards, and one enclosure. These major components are of good quality, which could helps to prolong the lifetime of themselves and that of the AVR voltage stabilizer.
