Dimmer DM-400B (Lighting Controller) is an innovative product of digital technology Leading Edge & Trailing Edge, specially created to fully cover the needs for regulation of lighting intensity and for energy saving, using alternative type of lamps such as LED (dimmable LED), economy lamps (dimmable CFL ) and previous generation light bulbs (Resistive - Halogen).
It is a totally safe, reliable, and aesthetically shaped product made of special integrated circuits of cutting-edge technology and of resistant plastic parts for difficult conditions of operation and usage.
Handling: Dimmer DM-400B operation features:

  • Input for wired remote control from one or more parallel buttons for adjusting the lighting intensity (ON / OFF by briefly pressing the button and stretch the lighting - Dimming with a long press).


Function Selection: Leading Edge to Trailing Edge and conversely is accomplished by  long pressing  the button for more than  fifteen (15) seconds.


Lowest threshold setting: DM - 400B enables the user to preconfigure the minimum point of brightness for Dimmable Led lamps, if required. This process is achieved by adjusting a potentiometer (trimmer) located on the product.
