Dimming actuator for brand switches – trailing edge

Dimmable lights retrofitted invisibly.

An efficient home office, a relaxed TV evening or dinner with friends and family: You can significantly influence the ambience in your smart home with the lighting mood. Integrate your lights quickly and easily into your smart home with the Homematic IP dimming actuator. This allows you to match the ambience of your four walls to any event.

Switching and dimming lights the intelligent way

You can easily adapt the lights to your everyday life to create individual lighting moods. And you can do it at any time you like - also depending on events such as sunrise and sunset.

You can switch and dim almost all conventional luminaires almost steplessly as you wish: combined in a group, individually automated, via Homematic IPpushbuttons and remote controls, by voice command, directly on the device or via your smartphone – at home or when you're out and about.

Invisibly installed in the existing design

The dimming actuator is simply integrated into existing switch series and invisibly covered by existing frames and rockers.

With its compact design, the dimming actuator can be easily installed in standard flush-mounted boxes. Wiring is particularly easy and safe thanks to the screwless terminals. Integrate the dimming actuator into leading manufacturers' switches. We supply you with the corresponding adapters for this.

Quiet and versatile

The dimming actuator works completely silently together with many different modern light sources and also those with particularly low current loads.

Matching light sources:

Dimmable LEDs
Dimmable economy lamps
Traditional incandescent lamps
HV halogen lamps
LV halogen lamps with an electronic transformer

Smart alarm clock

A relaxed start to the day: Be woken up gently by dimmable lights. The dimming actuator switches the lights on automatically at sunrise or at a desired time of the day.
