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 on the Link Interface.

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.
LEDs flashing or glowing when off
The outputs of the Dimmer Extension are equipped with capacitors for interference suppression. This results in a voltage being measurable at the outputs even when the outputs are switched off, especially without a load. The voltage disappears with even a low load, as there is virtually no power available here.
However, some low-power LED lamps are so sensitive that this can cause occasional flashing or slight glowing. In such a case, use other lamps or a higher number per channel, or switch them off via an additional relay contact.
Speed control of motors↑
The Dimmer Extension can also be used for speed control of motors via leading edge dimming.
However, only certain motors are suitable for this.
Only use this if you have experience with speed control of motors by phase cutting and if it is known that the motor type used can be controlled by leading edge phase cut and that no dangerous voltage peaks occur.
If the motor is not suitable, this can damage both the motor and the Dimmer Extension!
Such damage is not covered by warranty.

| Serial Number | Specifies the serial number of the device. For Extensions: Enter 'Auto' to automatically pair an extension with unknown serial number. This can only be used if there is only one Extension of the same type. Save into the Miniserver, in order to pair the Extension. Afterwards the program must be loaded from the Miniserver to transfer the actual serial number of the Extension into the program. |
