Shanghai automation SCR Voltage RegulatorDetails：

ZK-1 Shanghai automation SCR Voltage Regulator is used with current output instruments and SCR components, Can serve as a single-phase or three-phase voltage power adjustment.

ZK-1,ZK-0, ZK-3, ZK-3A, ZK-3B, ZK-03, ZK-03A, ZK-03B, ZK-30 SCR Voltage Regulator, thus automatic control furnace temperature of resistance furnace (or induction furnace) , it has high regulation accuracy and strong anti-jamming capability, to adapt technological development and market needs, user use these improved products comfortably. The improved ZK series instruments with IC make the increase of Trigger pulse amplitude, width, conduction angle

Of instruments, improve the reliability of instrument, make application more widely.
