Product description

The cooling controller ST181-LM4KAR.112 is a control unit specifically designed for 24V DC ventilation adjustment. The maximum ventilation power is 10W. The number of revolutions can be decreased to 20% and thus create a minimum air speed. Due to the galvanic separation of the ST181-controller the low-voltage ventilator can also be safely operated in a wet environment.

The two gas-tight relays for 16A each (engine load max. 1HP) supply the compressor, lighting or other necessary exits.
Networking of the controller takes place via the ST-Bus interface.
