Product description
DSP series high-precision programmable DC switching power supply consists of high-power IGBT, full-bridge inverter, power factor correction circuit, high-frequency transformer, rectification and filtering to form the main loop. The high-performance digital signal processing controller is the core to form the control system. The intelligent control operation panel is used as the man-machine interface to communicate with the host computer to realize intelligent 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 above 95%) 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 12KW. 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)
Product use occasion: 
Suitable for laboratory, electronic equipment aging, motor soft start, motor excitation, electric heating, capacitor aging, battery charging, crystal growth, communication equipment, factory electrical, environmental testing and other occasions.
