We recommend to install the module in a well ventilated area on a larger metallic piece for optimized cooling and durability. If the modules is used with our heater, no additional cooling measures are required.
If a load with a current draw of over 5A (10A max.) it run on the module, the installer needs to make sure that the metallic base plate of the module will not heat to more than +70°C under highest load (the connected load runs at max. power).
The operating voltage of the module must be between 9 – 28 V and come up to the operating voltage of the connected load. Example: When operating a 12 V motor the operating voltage must be 12 V.
The operating voltage (e.g. from the battery) and the load (e.g. direct current motor) have to be connected according to the drawing. 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). If the cable is too thin or too long power losses will occur in the cable and the connected motor runs slower. Furthermore, there is the risk that too thin cables will become hot because very high currents flow.
It is absolutely necessary to connect a fuse 10 A in series according to the connecting diagram!
