This listing is for a 5A DC-DC adjustable step-down module with a built-in LED voltmeter display. Turn the leftmost (see diagram) bronze screw to change output voltage. Clockwise increases, anticlockwise decreases. On first use, you may have to turn it anticlockwise a number of times until the output starts changing. Turn the rightmost (see diagram) bronze screw to limit the output current. Clockwise increases, anticlockwise decreases. Features include:
Note that the input voltage must be higher than the output voltage. This is a step-down converter. |
