Generater Automatic Voltage Regulator AVR POW50A 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.
