24V 100A reverse rectifier transformer Features
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
24V 100A reverse rectifier transformer for electrolysis:
THE DIFFERENCE BETWEEN SCR & IGBT SWITCH RECTIFIER
1, efficiency
SCR: 70%
IGBT:90%
2,Transformer
SCR:Power frequency transformer, large volume about 200kg
IGBT:without Power frequency transformer
3,Energy saving efficiency
SCR: bad
IGBT: energy saving about 15%-30%
4, start/stop with load
SCR: can’t
IGBT: can
5,control circuit
SCR:Complex, request synchronous and difficult to integrate
IGBT:use the simple integrated circuit board, and anti-corrosion treatment completely closed.
6,constant current accuracy
SCR:＜5%
IGBT:＜1%
7,cooling way
SCR: water/oil/air cooling
IGBT:water/air cooling
8,work frequency
SCR:50HZ
IGBT:20KHZ
9,control way
SCR:Phase shift trigger
IGBT: PWM
10,output DC
SCR:half wave
IGBT:High density DC square wave
11,Disturbance to power grid
SCR: large,Not easy to eliminate
IGBT: small,easy to eliminate
12,size and weight
SCR: large size and heavy
IGBT: small and light weight
13,Allowable fluctuation range of input voltage
SCR: ±10%
IGBT:±15%
10V 300A rectifier for zinc plating 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 |
