In addition to regulating the generator voltage, the AVR circuit includes protection features detection loss and low speed. The excitation power is derived directly from the generator terminals. Description: SX460 is a half-phase controlled thyristor type automatic voltage regulator (AVR) and is part of the excitation for a brushless generator. Positive voltage accumulation from residual levels is ensured by using efficient semiconductors in the AVR power circuit. The connection of a remote voltage regulator is provided, which allows the user accurate control of the output of the generator., Weight: 0.73083239853 pounds, Manufacturer: Rtxbvg
