Positive voltage accumulation from residual levels is ensured through the use of efficient semiconductors The SX460 is a half-phase controlled thyristor-type automatic voltage regulator (AVR) and is part of the excitation for a brushless generator. in the AVR power circuit. In addition to regulating the generator voltage, the AVR circuit includes detection loss and low speed protection functions. The excitation power is derived directly from the generator terminals. Connection of a remote voltage trimmer is envisaged, allowing the user accurate control of the output of the generator., Weight: 0.64815905028 pounds, Manufacturer: Rtxbvg
