?Plastic panel, beautiful and generous. Hand-held design, easy to carry.Voltage and current are adjusted roughly and finely to adjust voltage and current accurately. ?Constant voltage, constant current automatic conversion, can be used as a constant voltage source, also can be used as a constant current source. ?Perfect protection functions: adjustable overvoltage protection (OVP), short circuit current limiting protection (OCP), overtemperature protection (OTP), overpower protection (OPP). ?The circuit design is reasonable, the key components are imported and can be used at full load for a long time. PWM switch mode, light weight, high efficiency, energy saving and environmental protection. ?Scope of application:Aging test of factory products: such as DC motor, DVD, audio, resistor, capacitor and other products.Battery Charging Industry: Perfect application in battery charging industry, first provide constant current charging, then convert to constant voltage trickle current charging, or set overvoltage protection, implement automatic charging, full automatic stop.Inverter industry,LED manufacturing industry,Other occasions requiring DC regulated power supply etc.
