Product Description

AS480 DIESEL GENERATOR AVR Power stabilizer AVR  for Stamford PI PO series
Power stabilizer AVR AS480 for Stamford PI PO series 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. Which is linked with the main stator windings and the exciter field windings to offer closed loop control of the output voltage with load regulations of +/- 1.5%
