DNDT Functional Features
The DNDT series intelligent thyristor switch module is a power device used for fast switching of power capacitors. The product mainly consists of bidirectional thyristors, trigger circuits, absorption circuits, temperature protection switches, heat sinks, and cooling devices. This switch has no inrush current, good conductivity, fast response speed, builtin over temperature protection switch, and a switch that control the automatic operation of the fan during switching, ensuring the long term safety and stability of the product This product is suitable for frequent switching of capacitors for dynamic compensation and harmonic control.
Main Features
Zero crossing switching and no surge current will not cause voltage flicker in the power grid.
Using high-quality thyristor modules, with high reliability, stability, optoelectronic isolation, strong ant-interference ability,and rapid response (20ms).
The LED signal light displays the on/off status of the cooling fan for the defective product, and the fan is automatically controlled to start and stop. It has an all metal shell with built-in over temperature protection and good heat dissipation.
Touchable secure connection technology operates without noise or mechanical damage, greatly extending its service life and making maintenance simple and convenient.
