Product description

The cooling controller ST181-VL4KA.12 is a control unit specifically designed for 12V 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 three switching outputs with our proven 16A relay allow complete operation of the cooling circle as well as further additional features, as for example the lighting and many other functions.
The timer allows a 1-week time management for the defrosting periods as well as for setting the cooling chamber temperature at night or on the weekend. With regard to the parameter level, programming of this timer is easy and user-friendly. The actual time can be re-set simply directly on the operator surface.
