Stepless speed controller for DC roof fans. Dial the Le Mans down for silent night ventilation or run it flat out on hot days. 25 A continuous, waterproof housing, one unit can drive several ventilators.

The Speedcontrol lets you run any of our DC roof fans at exactly the speed you need: from a silent trickle to full power. The range is stepless from 0 to 100%, and at the zero position the unit draws no current at all.

Rated for 11 to 30 VDC and 25 A continuous (30 A peak), it works on 12V and 24V systems and can control one or several ventilators at once. The housing is waterproof, the unit is current-limited and transient-suppressed, and it connects with standard 6.3 mm flat connectors. Supplied with potentiometer knob and instructions.

Can I use it together with a 3-way switch?

Yes. The switch selects blow / off / suck, the Speedcontrol sets the speed. The slower the fan runs, the quieter it is and the less air it moves.

Goes well with the Speedcontrol.
