Dimmaktor Eltako FUD14 RS485, phase-cut dimmer actuator, max power 400 W

Eltako FUD14 RS485 is a phase-cut dimmer actuator with RS485 interface for controlling lighting loads up to 400 W. It supports leading and trailing edge phase-cut dimming and integrates into building automation systems via RS485 communication, making it suitable for retrofit and new installations where adjustable light levels and scene control are required.

Advantages

The FUD14 RS485 offers compatibility with common phase-cut dimmable lamps and supports both leading and trailing edge control. Its RS485 interface enables reliable communication with building control systems and allows centralized control and integration into automation scenarios. Compact design simplifies installation in distribution boxes and electrical panels.

Key specifications

How to use

Install the FUD14 RS485 in a suitable electrical enclosure following local wiring regulations. Connect the RS485 bus to the building control system for communication and configure the actuator parameters according to the system documentation. Wire the lighting load to the dimmer output and verify compatibility of lamps with phase-cut dimming. Test scenes and dimming ranges after commissioning.

Recommendations

Use the actuator with lamps and drivers specified as phase-cut dimmable; avoid exceeding the 400 W maximum load. Ensure RS485 wiring follows recommended topology and termination for stable communication. For mixed lamp types or complex installations, verify behavior in a test run before final commissioning.
