Eltako Universal Dimmer Switch Power MOSFET 400W EUD15NPN-UC (21100808)

Dimmable LED lamps often flicker or drop out at low brightness when connected to a standard dimmer. The Eltako EUD15NPN-UC universal dimmer switch solves this by using Power MOSFET technology to provide smooth, stable dimming for incandescent, halogen, and dimmable LED loads up to 400 W. It works with momentary pushbuttons and accepts a universal control voltage of 8-230 V UC, so it integrates into many existing installations.

Who is it for

Electricians and advanced DIYers who need a reliable flush-mounted dimmer for mixed lighting circuits, especially where LED compatibility and low minimum loads are critical.

Main features

• Universal dimming for R, L, and C loads with automatic detection, plus manual LV/LC selection for optimal LED performance.
• Power MOSFET design handles up to 400 W incandescent/halogen or 400 W dimmable LED, with a minimum LED load of just 1 W.
• Soft ON/OFF and memory function for comfortable lighting and recall of last brightness level.
• Electronic overload protection and overtemperature shutdown for safe operation.
• Adjustable minimum brightness to prevent flicker at low levels.
• Flush-mounted design with screw terminals for secure wiring.

Tips

For best LED dimming results, use the manual LV/LC selection if automatic detection causes flicker. Ensure the total connected load does not exceed 400 W and that the minimum LED load is at least 1 W to avoid unstable behavior.
