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
