Thyristor type Automatic Voltage Regulator is featured with soft start circuitry to provide a smooth controlled build up of generator output voltage. The Automatic Voltage Regulator is a three phase, thyristor type voltage regulator that forms part of the excitation system for a brushless generator. The Automatic Voltage Regulator operates on a power supply rate of 170-220 V AC. Thyristor type Automatic Voltage Regulator functions at a nominal frequency rate of 100-120 Hz.
