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.

Cabinet: HF switching Rectifier SMR with timer adopts magnetic cut links,
reduce eddy current losses, and cabinet as a whole spray painting | Structure: HF switching Rectifier SMR with timer with reasonable structure
design, isolated the inverter part and , rectification part ,
convenient to disassemble and maintenance |
Radiator: radiator capacity expanded 1.5 times,make sure better cooling
effect | switch control way: adopt full bridge phase shifting soft switch,reduct IGBT loss,save
engergy |

defense lacquer | IGBT: IGBT capacity expanded 3 times,make the power supply more reliable |
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 |
