ZUKCS-3f Capacitive contactless switch

Introduction

ZUKCS series reactive power compensation regulator is an electronic power device module that can quickly switch power shunt capacitors. Its electrical structure is mainly composed of high-power anti-parallel thyristor modules, isolation circuits, trigger circuits, and synchronous circuit protection circuits. It is composed of driving circuit, and is equipped with connecting terminals to control the switch on or off, and control logic voltage OV (off), 12V (on). This switch has the characteristics of simple installation, convenient maintenance, fast switching (dynamic response time 20ms), capacitors do not need to be discharged, switching without inrush current, noise-free operation, stable and reliable operation, and lack of phase protection. It is an ideal device for switching capacitor banks for reactive power dynamic compensation devices.
