   Product details
ZK Series Thyristor Voltage Regulator




I. scope of application
    ZK series controllable voltage regulator XCT- 1 9 x 1/2, XFT- 1 9 x 1/2, TA-09 x 1/2, TE-090 x 1/2, XTM-290x1 / 2, FESA-890x1 / 2 instruments and ≤ KP-200A (three-phase 600A) thyristor components can be used as single-phase or three-phase voltage and power adjustment, so that the furnace temperature of the resistance furnace (or induction heating furnace) can be automatically control. It has high adjustment accuracy and strong anti-interference ability. In order to meet the technical development and market needs, it is convenient for users to have improved products in this series. The improved zk series instruments use integrated circuits to increase the amplitude, width, and conduction angle of the instrument's trigger pulses, improving the reliability of the instrument and making it more widely applicable.
ZK—1 single-phase phase-shift trigger ZK-03 three-phase zero-crossing trigger (high-power resistance furnace) Note: ZK-19pZK-50ZK-100ZZ200ZK-03 is a three-phase half-control and its improved type is half-control or full-control.
