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.

Application ofHF switching Rectifier SMR :
Mainly used in non-ferrous metal electrolysis: aluminum, magnesium, zinc, lead, copper, manganese and manganese dioxide; gold, silver and other metals smelting; neodymium iron boron rare earth smelting; hard alloy, diamond smelting; salt water, potassium electrolysis to produce caustic soda, potash, sodium system; fire electrical heating materials, and other types of high-power DC power supply.
| 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 |
