High Frequency Switching Power Supply (500A~4000A)

● High reliability,The main power devices are high-quality devices from well-known manufacturers at home and abroad. Three-phase rectifier bridge module of Japan's SanRex , IGBT of Germany's Infineon and imported high-frequency rectifier devices. High-quality power devices provide strong guarantee for the high reliability of the whole power supply. 

● Soft turn-off technology to reduce the loss of switching IGBT and extend the service life.

● Digitally controlled PWM, which can be counted and controlled one by one, has the function of magnetic balance correction for each pulse.

● Excellent corrosion resistance. The mechanical structure with isolation function is adopted, and the control circuit adopts the "three prevention" treatment measures to prevent salt ,fog and acidification.

● Perfect protection .It has soft start, overcurrent,overheat,sound and light alarm functions，etc.

● The function of stabilizing current or voltage can be selected according to the process requirements. When the grid voltage fluctuates by 10% and the load remains unchanged, the output deviation is ≤ 1%.

● Power components work efficiently without noise. Local and remote control can be realized through PLC or field bus and computer interface and easy to operate. The timing, ampere-hour and temperature control can be setted.

● Small size, light weight, high efficiency and high control precision, saving electric energy and using space.

● The equipment can run continuously with full load for a long time in harsh environment, and adopts full water cooling or air cooling. Working temperature rise of transformer less than 60k; The working temperature rise of igbt and diode is less than 60K.
