Product Features    

1.Introduction:

SX460 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 inthe 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% 

Stability adjustment

Under frequency roll off adjustment
