Product Description


HF switching Rectifier SMR 12v 400a with 380v 3 phase AC input ​ Specification and parameter



Description of high frequency electrolytic power:

switching Rectifier SMR main circuit includes main transformer, power rectifier components and some other testing, protection devices. Power supply main transformer function is to reducing AC current/voltage to the plating technical process required voltage value. Thyristor rectifier uses frequency (50Hz/60Hz) transformer, while high-frequency switching power supplies using high frequency (10 ~ 50kHz) transformer. Detection devices include voltage meter, current transformers. Protection device is mainly used for power rectification components over-current protection. The control circuit includes a thyristor or IGBT, trigger control circuit, power soft-start circuit, over-current, over-voltage protection circuit, power phase protection circuit.

1, Placing rectifier and keep the body stability; ensure good ventilation.
2, Checking anodizing rectifier out cover if loosing.
3, Connecting shell to ground to prevent static electricity.
4, Conecting the AC input wire
5, Connecting the DC output copper bars
6, Connecting the rectifier remote control box,if local control ,skip this step
7, Turn on air switch, then the fan starts to rotate and the power indicator light.
8, Clockwise rotation adjustment button, voltmeter degree increases, working indicate light lighting.
9, Adjust knob to maximum, then the voltmeter should indicate the rated voltage, current meter indicates the load volume accordingly.
10, Disconnect the air switch, turn off the rectifier
