USB Powered Adjustable Power Supply (0.7~27.5 Vdc)

This flexible buck/boost power supply plugs directly into a Type A USB socket to give you an varible voltage DC power supply.

With 5v input you can get 1~24 Vdc output at up to 3 watts power. Voltage is adjusted via a 30-turn potentiometer. The output voltage is displayed to 1 decimal place on the three digit LED display.

Use cases: powering up sensors, simple signal generation (0~10Vdc / 4-20mA) - use your multimeter as the reference, simple electronics test bench power supply.
