erformance characteristics:
1.Stabilized voltage and current. Digital keyboard operation, voltage, current from zero to rated value adjustable, output voltage and current value set in advance.
2.High precision, low ripple. The DC power supply is controlled by peak current, and has good load and power regulation rate, and the output voltage and current precision are high.
3.High efficiency. The soft switching technology with international advanced level makes the power supply high efficiency, low noise and high reliability; 
4.The protection function is complete. There is an overload protection circuit inside the power supply to ensure the normal operation of the power supply equipment and the safety of the load.
5.Output display. The voltage and current are displayed with high precision LED digital meter.
6.Digital control. All digital control, voltage and current can be realized through digital programming; all the calibration is digital calibration, stable and reliable.
