SBW series compensated AC voltage regulator mainly consists of compensation circuit, voltage detection, servo motor control circuit and deceleration transmission mechanism, electric switches and their operating circuit, current / voltage measuring and protection circuit. Among them, compensation circuit, voltage detection, servo motor control and deceleration transmission mechanism make up the output voltage auto-compensation system, which can automatically keep output voltage stable when grid voltage fluctuates or load variates.
SBW series products have advantage of traditional electric AC, inductive and magnetic-saturation stabilizer, and are featured with other advantages of high power, high efficiency, without waveform distortion, stable voltage regulation, convenient maintenance and reliable operation.
