High Quality Automatic Voltage Regulator AVR SX440 For Brushless Alternator
AVR 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 Stamford AVR Card SX440 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.
