The TKB TZ67 is a dimmer plug that can be placed between a wall outlet for Schuko Plug and electric devices, plugged in by cord. It can dim resistive loads up to 300 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. It is therefore only possible to dim incandescent lamps and high voltage halogen lights. Low voltage halogen lights, LEDs and CFLs must not be attached. Dimming is controlled wirelessly using Z-Wave or locally applying a button. A blue LED indicates the dimming status.
