To connect a standard 3-pin connector fan to the module, use one of the following adaptor cables:
KAB-HSP 200 mm (PN 96079-0000-00-0)
KAB-HSP 40 mm (PN 96079-0000-00-2)
If the input voltage is below 12 V or equal to 12 V, then the maximum supply current to the on-board fan connector is
350 mA and the fan output voltage is equal to the module input voltage. The maximum supply current is limited to
150 mA if the input voltage is more than 12 V but less than the maximum voltage input of 20 V.
Always check the fan specification according to the limitations of the supply current and
supply voltage.
