High Frequency Switching Power Supply 500A~4000A - China Suppliers and Factory with Air/Cooling Options
Product Feature
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.
The mechanical structure with isolation function is adopted, and the control circuit adopts the "three prevention" treatment measures to prevent salt, fog and acidification.
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.
