AVR 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 in the power circuitry of the AVR.
