Alternator Voltage Regulator AVR for Generator 

An automatic voltage regulator AVR is a solid-state electronic device that automatically maintains generator output terminal voltage at a set value. It will maintain constant output voltage as the load increase or decreases. The AVR is part of the alternator's excitation system.

We supply Kirlsokar AVR, Stamford, Joyti, Kirloskar Green, Leroy Somer, AVR for Brushless Alternators, Slipring (Brush) type AVR, Avr for parallel operation synchronization of Diesel Generator, Custom specification AVR, Diode plate, Diode, etc.
