Product Description
Diesel Generators Engine Parts Automatic Voltage Regulator AVR SX440 for Cummins
Description:
Cummins Generator AVR - SX440
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.
