Applications:

This module can be applied to a buck devices, such as batteries, power transformers,

DIY adjustable power supply, 24V car laptop power, industry buck equipment,

12V to 5V, 24V to 5V, 24V to 12V, 36V to 24V and so on.

Notes: If you select 5V-24V version.

can not adjust the voltage, it may due to potentiometer is in too high resistance.
need to adjust the potentiometer dozens times by turning anticlockwise, so that you can adjust the output voltage
