Dimmer module for wirelessly dimming LED light bulbs and other types of light bulbs. As well as dimming lamps and lights wirelessly with a Nexa remote control you can also connect a spring-loaded on/off switch to the dimmer module (push-button switch spring sold separately). Short-presses on the switch will turn it on/off and long-presses on the switch will adjust the light intensity. You decide if you want to control the lights wirelessly with a remote control or with the existing wall switch.

The Nexa MWMR-251 build-in dimmer supports Nexa Smart Mode, a new feature that allows you to save up to 3 favourite settings that you simply activate by pressing once, twice or three times on a Smart Mode compatible remote. Using one setting you can manage several actions in a row with only one command, i.e. you can turn on, dim and turn off as many devices as you like with the same command.

MWMR-251 is a universal dimmer that works with dimmable 230 V LED bulbs (3–120 W), 230 V halogen and incandescent bulbs (25–250 W), electronic transformers (20–250 W) and conventional transformers (40–250 W). It comes set up for leading-edge dimming but can be changed for trailing-edge phase dimming if required. The minimum brightness/dimmer level can also be adjusted depending on the choice of light bulb.

The Nexa built-in dimmer is intended for permanent installation in wall/ceiling boxes. Requires both phase and neutral.


Must only be installed by a competent electrician.
