The inputs and outputs are indicated on the PCB of the DC-DC converter. IN+ and IN- is the input, OUT+ and OUT- is the output.

*Note: The maximum output voltage may deviate by ±2V. We also recommend to never set the output voltage higher than 50V due to limitations of components. For long-term use, we recommend using a maximum of 25V DC on the input and setting the output voltage to a maximum of 35V DC.

**Note: The potentiometer is multiple turns. It may take a while before the desired setting is achieved. The potentiometer can turn about 25 times from start to finish.
