10kVA Generator Parts Automatic Voltage Regulator Alternator AVR GAVR-12A

10KVA Voltage Regulator Alternator AVR GAVR-12A is a half-wave phase controlled thyristor type Automatic Voltage Regulator and forms part of the excitation system for a brush-less 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. Which is linked with the main stator winding and the exciter field winding to offer closed loop control of the output voltage with load regulations of +/- 1.5%.TECHNICAL data:
