GAVR-20A gavr cf 20a gavr 20a black Universal AVR Automatic Voltage Regulator Generator controller for 500 kva generator diesel
GAVR-20A is a half-wave phase controlled thyristor type Automatic Voltage Regulator and forms part of the excitation system for a brushless 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. Positive voltage build up from residual levels is ensured by the use of proficient semiconductors in the power circuitry of the AVR.
