40V 7000A PULSE POWER SUPPLY electropolishing
description:
Electrolytic polishing refers to the finishing process in which metal products undergo special anodic treatment in a certain composition solution to obtain a smooth and bright surface. It can be used to prepare the surface of the product before electroplating, it can also be used for the finishing of the surface after plating, and it can also be used as an independent finishing method for the metal surface.

40V 7000A IGBT electropolishing rectifier Features
Cabinet:
Cabinet adopts magnetic cut links, reduce eddy current losses, and cabinet as a whole spray painting
Structure:
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
Main transformer:
adopts amorphous core,increase transformer efficiency,reduct the transformer temperature rise,cut the rectifier weight,improve the power supply stability, reliability
Core & Schottky diode:
core capacity expanded 1.5 times
schottky diode expands 4 times
Board :
all control boards did anticorrosion treatment with imported three defense lacquer
IGBT:
IGBT capacity expanded 3 times,make the power supply more reliable
40V 7000A IGBT electropolishing rectifier Installation
| 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 |
produce process :
From the beginning of the raw material to the selection, to the assembly, and finally commissioning. We will enforce the standards strictly. Before package, 24V 125A dc single output switching power supply with CE will be check again to ensure that it works normally.
