LED Light Dimmer 230V Din Rail Mount 872110 Hugo Muller

The Hugo Muller 872110 is a universal LED Light Dimmer that mounts on 17.5mm din rail inside a distribution board instead of sitting in a wall box. That matters on projects where the dimming has to be controlled centrally, or where the wall position only carries a simple push switch.

It dims by either leading edge or trailing edge, which is what makes it universal. Leading edge suits ferromagnetic transformers and older load types, while trailing edge is the correct method for electronic transformers and most modern dimmable LED lamps. Having both in one unit means the same part number covers a mixed lighting schedule instead of specifying a different dimmer per circuit.

The master slave function lets one dimmer control others on the same system, so a bank of circuits can be dimmed together from a single point. Load coverage runs across dimmable LED, incandescent, HV halogen, LV halogen through either transformer type, and dimmable compact fluorescent lamps, with the exact wattage limits for each listed in the tables below.

Common Applications

Centralised lighting control in apartment and villa distribution boards, hotel and office lighting circuits, retail and showroom display lighting, conference and meeting room scene setting, stairwell and corridor lighting, and retrofit projects where existing halogen circuits are being converted to dimmable LED.

Related Products and Categories

This dimmer sits in the Staircase Lighting Timer and Light Dimmer range, where you will also find staircase timers for corridor and stairwell circuits that switch on a timed delay rather than dim.

For the wider board control range, browse Digital and Analog Timers, which covers time switches, cyclic timers and astronomical timers for lighting schedules. Projects that need app or scene control rather than a rotary dimmer should look at the Lighting and Home Automation category.

FAQ,s

What is a din rail LED Light Dimmer?

It is a dimmer that mounts inside the distribution board on standard din rail instead of in a wall box. The wall position carries a simple switch or push button, while the dimming electronics sit centrally with the rest of the board.

What is the difference between leading edge and trailing edge dimming?

Leading edge cuts the start of each mains half cycle and suits ferromagnetic transformers and traditional loads. Trailing edge cuts the end of the cycle and is the correct method for electronic transformers and most dimmable LED lamps. The 872110 supports both.

Will it dim any LED lamp?

Only lamps marked as dimmable. A non dimmable LED will flicker, buzz or fail if connected to a dimmer. Check the lamp wattage falls within the LED load range in the table above.

What does the master slave function do?

It lets one dimmer act as the master and control additional dimmers as slaves, so several lighting circuits can be dimmed together from a single control point.

How much din rail space does it need?

17.5mm, which is one standard module width on the rail.

Can it be installed outdoors?

No. The IP 20 rating means it is protected against solid objects but not water, so it must be installed inside an enclosure or distribution board.
