High Frequency Switching Power Supply (500A~4000A) - Trusted China Suppliers & Factory for Reliable Performance
Product Feature
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: Reduces the loss of switching IGBT and extends 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 current/voltage: The function 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 & Quiet: 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 set.
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 environments, and adopts full water cooling or air cooling. Working temperature rise of transformer is less than 60K; the working temperature rise of IGBT and diode is less than 60K.
