Product Features:

1Switching power supply design, stable and reliable, lightweight and beautiful, using SMT production technology.

2Equipped with backlit LCD display output,The voltage adopts a multi turn potentiometer to accurately adjust the output voltage value.

3. Constant voltage and constant current automatic conversion, can be used as a constant voltage source or a constant current source.

4. Reasonable circuit design, key components *, can be used at full load for 24 hours.

5. PWM switch mode, high efficiency, energy-saving and environmentally friendly, performance close to linear power supply, efficiency far higher than linear power supply, can replace linear power supply for the vast majority of occasions.

6. Intelligent temperature controlled fan (working up to 50 ℃) effectively reduces noise and extends the lifespan of the fan.

7. Current limiting protection function

Application scope:

1Factory product aging: such as the aging of DC motors, DC fans, car DVD players, car speakers, resistors, capacitors, and other products.

2Battery Charging Industry: * is applied in the battery charging industry, providing constant current charging first, and then converting to constant voltage trickle charging to prevent overcharging, protect the battery, and effectively extend the life of the battery.

3Inverter industry: Avoiding the potential problem of poor contact of contacts when linear power relays trip, with extremely fast response speed, meeting the requirements of instantaneous load changes.

4LED manufacturing industry: LED testing, aging.

5All other occasions that require a DC stabilized power supply.
