High Frequency Switching Power Supply (500A~4000A) - China Suppliers & Factory with Advanced Technology

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: Used to reduce the loss of switching IGBT and extend the service life.

Digitally controlled PWM: Can be counted and controlled one by one, featuring 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.

Stabilizing function: 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%.

Efficient & Smart control: 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.

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

Continuous operation: 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.
