The Duwi 064398 is a dimmer plug that can be placed between a Schuko wall outlet and electric devices, plugged in by cord. It can dim resistive loads up to 400 W. The device is IP 20 rated and can therefore only be used in dry environments. For dimming the devices apply leading edge phase cutting with a special alignment algorithm for inductive loads. It is therefore possible to dim incandescent lamps, high voltage halogen lights and low voltage halogen lights with traditional transformer. Low voltage halogen lights with switching power supply, LEDs and CFLs must not be attached. Dimming is controlled wirelessly using Z-Wave or locally applying a button. A three color LED indicates the dimming status.
