PIN
DESCRIPTION

IN+
Input voltage – positive pole.

IN-
Input voltage – negative pole (ground).

OUT+
Output voltage – positive pole.

OUT-
Output voltage – negative pole (ground).

The output voltage is selected from 3.2 V to 35 V using a potentiometer. Note that this is a voltage step-down circuit, so the output voltage cannot be higher than the input voltage.
Features:

Input: DC 3.2 V to 40 V (input voltage must be higher than the output voltage)
Stable output, the output voltage is DC 3.2V to 35V, continuously adjustable, maximum output current is 3A.
LED indicator output.
Adjust the screw on top of the potentiometer clockwise or counterclockwise to increase or decrease the output voltage.
With reversed polarity protection and short circuit protection, more safer to use; the display is very accurate.
