SYNERGY21 LED Controller EOS 08 KNX Push-button 8-fold

The SYNERGY21 LED Controller EOS 08 KNX Push-button 8-fold is a versatile KNX device designed for controlling LED lighting systems. It combines a 4-channel constant voltage LED controller with 8 integrated push-button inputs, enabling direct switching, dimming, and color control without additional sensors. Ideal for smart building installations, it supports RGB, RGBW, Tunable White, and single-color LEDs, and is configured via ETS software.

Advantages

Integrated push-button inputs eliminate the need for separate input modules, saving space and installation effort. PWM dimming ensures flicker-free operation, while overload protection guarantees long-term reliability. The flush-mount design fits behind standard switches or sockets, maintaining a clean aesthetic.
