The AD1423 is a dimmer plug that can be placed between a British Standard wall outlet for Plug Type G 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. Therefore, it is 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 red LED indicates the dimming status.
