Contactless Voltage Regulator

Main Features: The DJW and SJW series single-phase and three-phase microcomputer non-contact compensation type power voltage stabilizers integrate non-contact switching, compensation transformer, and digital microcomputer control AC voltage stabilization technologies. They feature high efficiency, energy saving, rapid regulation, three-phase independent adjustment, automatic output balancing, and no mechanical faults. They also include self-diagnosis, self-protection, self-recovery, overvoltage, undervoltage, overcurrent, and phase loss fault protection functions, and are equipped with intelligent interfaces for remote monitoring. Widely used in broadcasting and television systems, unmanned microwave communication stations, industrial control machines, computer systems, industrial equipment matching, and other places requiring stabilized power supply.
