    Stamford AVR SX440 Automatic Voltage Regulator

Specifications

SX440 is a half-wave phase-controlled thyristor type Automatic Voltage Regulator (AVR) 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 features. Excitation power is derived directly from the generator terminals.

 

Positive voltage build up from residual levels is ensured by the use of efficient semiconductors in the power circuitry of the AVR.
