Features: SX460 is a half-wave phase-controlled thyristor type automatic voltage (AVR) and forms part of the excitation system for a bruch-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.Positive voltage builds up from residual levels is ensured by the use of efficient semiconductors in the power circuitry of the AVR. Runs freely in high-temperature environment, responds extremely fast, builds voltage quickly, stable and reliable, giving you a fine quality experience.
