Dimmer Extension

The Dimmer Extension features 4 Output channels for dimming suitable mains voltage luminaires.

Each channel can be set to trailing edge or leading edge dimming, the Dimmer Extension is thus suitable for resistive (incandescent), capacitive (ELV) and inductive (MLV) loads.

Additionally, 8 digital inputs for 24V are available.

Commissioning↑

The Dimmer Extension is installed on a DIN rail in a suitable enclosure.

Connect the power supply and Link communication to the Miniserver.

Connect the loads to the outputs as shown in the example above.

In case of large loads or multiple dimmers, it is advisable to spread the load across several phases as shown in the wiring example. However, a single-phase supply is also possible.

Ensure sufficient air circulation to allow the generated waste heat to dissipate, especially at high workloads.

The Extension starts after switching on the power supply, and the status LED will flash orange after a short time when the connection to the Miniserver is established.

Then follow the pairing procedure

Please observe the recommended dimming type and load limits!
Only use luminaires that marked as dimmable!
Load type Dimming type Max. load AQ1 Max. load AQ2/3/4 Minimum load
Incandescent bulbs Trailing edge 400W 210W -
Mains voltage Halogen lamps Trailing edge 400W 210W -
Low voltage halogen lamps with electronic transformer (ELV) Trailing edge 200VA* 105VA* -

Mains voltage LED fittings (retrofit, LED bulbs) Trailing edge or leading edge (rare) 200VA 105VA 50VA for leading edge/inductive
Low voltage halogen lamps with magnetic transformer (MLV) Leading edge 400VA** 200VA** 50VA
*The sum of the nominal load of the ballasts, LED drivers or transformers is relevant, not the nominal load of the actual light.
**A magnetic transformer must be loaded with at least 80% of it's capacity!
The ballasts, LED drivers, electronic transformers etc. used must be mains voltage dimmable!
If in doubt, the manufacturer of the luminaire can provide information on the load characteristics (whether inductive or capacitive) and the recommended dimming method.

Notes on luminaires↑

Incandescent bulbs

Of all luminaires, incandescent lamps are the easiest to dim, this category can also include Halogen lamps and these are an alternative when the highest quality of light is desired and the energy consumption is acceptable.

Generally, incandescent lamps are always dimmable, even if they are not labeled as dimmable. However, for low-voltage halogen lamps, the transformer must be dimmable.

LED illuminant

In principle, all mains voltage LED luminaires marked as dimmable can be dimmed with the Dimmer Extension.
However, characteristics such as the dimming curve, dimming range, and flicker-free dimming can differ for every luminaire. There may also be batch-related differences in LED lamps.

It is advisable to use high-quality luminaires, which guarantee consistent quality and long-term availability.

If possible, test different LED luminaires for dimming quality before purchasing a large quantity.
