Power manual control element

1.Problem description:What is the function of the power manual control element? When the Ruida controller is working, how to connect this component to the power supply?
2.Analysis:1. Manually adjust the power of the power supply by rotating the potentiometer, so that the laser tube can output different sizes of laser (that is, artificially control the output power of the laser tube)
2. When the Ruida motherboard controls the power supply, it is impossible to use the whole set of components. You can connect the potentiometer separately to 5v (red wire), IN (blue wire), G (black wire)
3. So while the main board controls the power, the potentiometer can also be used to realize the secondary artificial control of the power.
