the power supply is specially used for micro arc oxidation treatment of aluminum, magnesium, titanium and alloy materials. It has all the advanced features of the fourth generation full inverter power supply. At the same time, the power supply can be used in parallel and can be separated. the equipment failure rate is low (the current of IGBT and charging and discharging capacitor is small, and it is not easy to explode, open circuit and other faults in the process of start-up and stop). The energy consumption is small (more than 10% less than that of single machine). It is convenient for parallel connection, maintenance and repair.

(1) Significant reduction of power consumption: starting according to the output power, the internal consumption of the system is low; the current of small power devices rises rapidly; the power factor is high, the operation cost is low, and the power consumption level under the same peak current is reduced to about 40%;

(2) All the basic output units of the new power supply can output in any direction, forming a bipolar pulse power supply with adjustable proportion.

(3) with the increase of production capacity, it is easy to expand the production capacity by adding unit modules;

the main controller is designed and programmed by DSP digital chip to realize the display and operation of color touch screen and control the downstream power supply freely. One main controller can control up to 8 power supplies at the same time;

2. the controlled power supply has independent display and control system (can operate independently), color touch screen operation, and choose to accept the control and operation of the main controller;

3. Controlled power supply: air cooling, with temperature probe to prevent temperature difference; controlled power supply: air cooling, with temperature probe to prevent excessive temperature difference;

the controlled power supply works in high-frequency inverter mode, the output stage works in high-frequency inverter mode, and the output stage uses high-power IGBT as chopper;

5. Cabinet size after combination: height 2000, width 900, depth 900 (actual delivery size shall prevail)

6. the controlled power supply can also be used in combination (in parallel), with total power = single power * number of units;

7.RS485

There are two models: 30A and 100A. The model is based on the average current of positive phase output, where the output current divided by 2-5A represents the processing capacity of each batch.
