Is made to easily have a motor run at a desired speed. With the DV11 you can set the speed of your suction device or extractor, for example. The DV11 is protected by a 6 Amp thermal fuse.
The thermal fuse ensures that the DV11 switches off with a short-circuit or overloading. The advantage of the thermal fuse is that when the problem has been fixed you only need to press the "reset"button and the DV11 starts working again.
The DV11 works on 230V. It has power of 6Amp/1350 Watt.
