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.
You now enjoy a station that only weighs 5 lbs, which is almost half the conventional linear power supply's weight and size. Thanks to our new and improved regulator design, we're able to upgrade the station to a heat sink cooling design without the need for a fan and bulky transformer.
