Product description

With the rapid development of China's industrial manufacturing industry, the demand for power supply capacity in the industry of motor debugging, electric railway, battery manufacturing, etc. is constantly increasing. The power switching power supply is small in size, light in weight, high in efficiency, reliable in quality, stable in performance and The advantages of easy maintenance and so on have become more and more popular among users. This series of power supply consists of high-power IGBT full-bridge inverter, power factor correction circuit, high-frequency transformer and Schottky diode. The main circuit is composed of high-performance digital signal processing controller. The intelligent control panel can be used. As a human-machine interface, communicate with the host computer to realize intelligence

control.

▲Main performance characteristics:

• Small size and light weight (equivalent to one-third of the volume and weight of a linear power supply or thyristor power supply of the same power)

• High efficiency (efficiency of over 92%) and stable performance.

• High power factor (power factor up to 0.95 or more)

• High precision (output voltage accuracy of 0.1% or more).

• Stand-alone power up to 500 kW. Choose the custom output maximum voltage and current value.

• Complete protection functions: over-voltage, over-current, over-temperature, phase loss, short-circuit automatic cut-off output, trip protection;

• Variety of parameter settings; optional rotary positioner or touch button

• Diversified display modes: LED digital tube display or LCD smart LCD display.

• Built-in short-circuit feedback feature, allowing long-term short circuit or short circuit (current limit).

• Output waveform customization: smooth DC, one-way pulse, bidirectional pulse, special waveform. Constant voltage, constant current, constant power control, control mode bumpless switching

• Real-time monitoring of the power system via the RS485 (or RS232) standard interface of the computer (optional)

• PLC interface function: Control the adjustable output of the rectifier through the signal output from the DA module of the PLC, as well as the monitoring of voltage, current and various operating parameters (optional)
