The KDGK-II high and low voltage switchgear power on test bench is used by high and low voltage switchgear manufacturers to conduct various power on tests on the produced high and low voltage switchgear before leaving the factory. It can provide various AC and DC power sources, facilitating the detection of switchgear and improving work efficiency.

This power supply consists of a fully controlled three-phase rectifier module, a phase-shifting trigger circuit, an automatic adjustment circuit, and an absorption circuit.

The transistor intelligent control module integrates complex automatic regulation circuits, thyristors, and trigger circuits into one. By adjusting the voltage of the control signal and changing the conduction angle of the thyristor, it achieves the function of regulating and automatically controlling the power supply.

The triggering circuit system, thyristor, and thermal conductive substrate are insulated and isolated from each other, with a dielectric strength greater than 2500V, making it safe and convenient to use. There is no phase sequence restriction at the input end of the three-phase rectification module. Suitable for resistive and inductive loads.
