Furthermore, there is the risk that too thin cables will become hot because very high currents flow. If the cable is too thin or too long power losses will occur in the cable and the connected motor runs slower. It is important to keep the cables as short as possible and also to employ cables with a sufficient cross-section (1.5 - 2.5 mm²). direct current motor) have to be connected according to the drawing. Example: When operating a 12 V motor the operating voltage must be 12 V. The operating voltage of the module must be between 9 - 28 V and come up to the operating voltage of the connected load. angle section, metallic plate) in such a manner that the metallic base plate of the module will not heat to more than +70☌ under highest load (the connected load runs at max. This is done by attaching it planely on a heat sink or bigger metallic piece (e.g. 10 A) the module with the metallic base area has to be cooled. In case of loads of more than 5 A (up to max. Therefore, it has to be mounted in a dry and well ventilated place. The module may heat depending on the load. The desired output may be adjusted (controlled) with the potentiometer after switching on the operating voltage.
