SJW: Micro-Controlled Non-Contact Compensation Three-Phase Voltage Regulator

Integrating the advance duplex winding compensation mode、non-contact Switch and microcomputer controlled regulating. It has high efficiency and energy-saving、 fast adjustment 、three phase automatic balanced,no mechanical malfunction or carbon brush wearing, also with the functions of delay、under/over voltage alarm and protection. Adopting the advanced duplex winding compensation technology which ensure little waveform distortion.
◆Adopting one-chip computer to control the thyristor and shifting combination for timing compensation adjustment enable it to realize the fast non-contact adjustment. Strong instantaneous overload capacity makes it available with various loads ◆Adopting one-chip computer split-phase control, it has the functions of delay starting-up, three-phase automatic balance addition adjustment, display、alarm and protection of open-phase、overrun and malfunction etc.
