Generator Automatic Voltage Regulator Brushless AVR GAVR-20A
General Features
Generator Automatic Voltage Regulator Brushless AVR GAVR-20A
AVR Universal ac regulator avr is a half-wave phase controlled thyristor type Automatic Voltage Regulator and forms part of the excitation system for a brusheless generator.
In addition to regulating the generator voltage, the AVR circuitry includes under speed and sensing loss protection to ensure safe, reliable control of the generator.
