ELTAKO RS485 Bus Universal Dimmer Actuator FUD14/800W up to 800W 30014006

Controlling lighting loads via a bus system often requires separate dimmers for different load types, complicating installation and commissioning. The ELTAKO FUD14/800W universal dimmer actuator solves this by automatically detecting the connected load and selecting the appropriate dimming principle, enabling smooth control of incandescent, halogen, dimmable LED, and mixed loads up to 800 W over the Eltako RS485 bus.

Who is it for

This actuator is intended for electricians, system integrators, and building automation professionals who need a compact, DIN-rail mounted dimming solution for residential or commercial projects using the Eltako bus system.

Tips

When using LED lamps, ensure they are dimmable and compatible with phase-control dimmers. Set the minimum brightness to avoid flickering at low levels. The actuator automatically detects the load type, but manual adjustment is possible via the bus system if needed.
