12V 5000A AC to DC plating power supply with air cooling remote control
Main working principle of AC to DC power supply:
Main circuit from AC to DC power supply:
The process is input from the AC current grid, and the output is the DC current output of the whole process, including:
1. Input filter device: its function is to filter out the impurity waveform existing in the power grid, and at the same time to prevent the impurities generated from AC to DC power supply from returning to the public power grid.
2. Rectifier and wave filter: AC current power supply of rectifier grid, direct and smooth DC power supply, used for next level conversion.
3. Inverter: convert the rectified DC power supply current into high-frequency AC, which is the core part of high-frequency switching power supply. The higher the frequency, the smaller the volume, weight and output power ratio.
4. Output rectifier and filter: provide stable and reliable DC power supply according to load demand.
On the one hand from the output take sampling, compare with the set standards and to control the inverter, change its frequency or pulse width output to achieve output stability, on the other hand, according to information provided by the test circuit, after protection circuit identification, provide control circuit for variety protective measures to whole machine.
In addition to providing protection circuit running in a variety of parameters, but also provide a variety of information display instruments.

2. Control mode: Local control or Remote control(the length of cable is determined by customers)
3. Japan IGBT(the default choice) or Germany IGBT are adopted
4. After being phosphated, galvanized and plastic sprayed, the chassis has excellent corrosion resistence function
5. Easy to operate and repaire
Other advantages
1. Cabinet
a: Adopting completely digitalized machining
b: Adopting cold rolled production of iron steel sheet, after phosphorization, zinc plating, plastic spray, the rectifier gets better structural strength and anti-corrosion.
c: Reasonable structure design, isolated inverter design, rectification part is convenient to disassemble and mend because of its neat assembling.
d: Radiator gets better cooling effect because of its 1.5 times capacity.
2 Electric control system
a: The rectifier adopts full bridge phase-shifted soft switch control, ensuring the lowest power loss of IGBT. The capacity of IGBT become 3 times bigger.
b: The main transformer. It adopts amorphous core to increase transformer efficiency and cool transformer, and not only can lighten rectifier weight, but also can strengthen rectifier stability and reliability. At its elementary stage, it adopts series blocking capacitor.
c: Magnetic deviation automatic correction circuit is adopted and the total power of magnetic core gets enlarged 1.5 times.
3 Schottky Barrier Diode
a: It has been expanded 4 times.
4 All the controlling boards get antiseptic treatment with imported lacquer.
How to install rectifier
| 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 |
