On-board Fan Connector
The fan connector powers, controls and monitors an external fan. To connect a standard 3-pin connector fan to the
module, use Kontron’s fan cable, see Table 4: Accessories.

If the input voltage is below or equal to 13 V, then the maximum supply current to the on-board fan connector is
350 mA. The maximum supply current reduces to 150 mA if the input voltage to the module is between 13 V and 20 V.
Always check the fan specification according to the limitations of the supply current and
supply voltage.
