This SMPS (Switch-Mode Power Supply) provides reliable power delivery and accurate readings. The power supply supports fine & coarse current adjustments from 0A to 5A and fine & coarse voltage adjustments from 0V to 30V. You can use this power supply for electronic projects, professional phone/laptop repairs, scientific projects, product R&D, electronic assembly lines, and more.

This power supply features an LED screen that shows the Voltage, Current, and Power parameters. A current display shows up to every mA (milliamps) / 0.001A and a voltage display that reads up to every 10 mV (millivolts) / 0.010V. This LCD screen also shows the status of C.C. or C.V. Modes, Over-Voltage Protection, and Constant Current Protection.

The power supply is equipped with a complete over-voltage and constant current protection circuit to help protect the components/devices that you're powering. In these modes, the power supply locks either voltage or current value in their respective modes to prevent overloading and protect the device at work.

Application: laptops, AIO, PC systems, printers, Intel NUC, MSI cube Mini PC and Gigabyte BRIX Ultra compact PC kits (except BRIX Pro and Brix gaming)

Input Voltage range: AC 100V - 240V (USA plug); output voltage: 19V, 6. 3a, 120 watt
