    Power Regulator

    SCR power regulator is used for regulating power & voltage and controlling temperature in heating constant temperature equipment and electric power system. It based on thyristor (power electronic device) and dedicated control circuit. ATO provides 3 phase 3 wire or 3 phase 4 wire SCR power regulator, with a variety of rated current or rated power for selection, control signals are 4-20mA, 0-5VDC, 0-10VDC (switchable or one of three options). In addition, digital SCR AC voltage regulator can continuously adjust the load voltage, and SCR AC voltage regulator module (vrm) and other products can meet diversified needs.
