AVR SX440 Automatic Voltage Regulator for brushless generator a half wave phase controlled thyristor type AVR
AVR SX440 Automatic Voltage Regulator for brushless generator a half wave phase controlled thyristor type AVR
In addition to regulating the generator voltage, the AVR 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 SX440
