Theben Universal Dimmer Meets KNX Challenge

Theben KNX Compatible Universal DimmerTheben’s KNX-compatible Universal Dimming Actuator has solved the problem of designing LED lighting systems in a world where there is no agreed standard for LED drivers.

It leaves designers free to choose lighting from any manufacturer, mixing and matching to build the best solution for each application which is, after all, the core principle and purpose of the KNX open protocol in the first place.

One of the key challenges for KNX systems designers at the moment – and indeed for any lighting designer - is the dimming of LED lights. There is no agreed standard for the design of LED drivers, and so every manufacturer is free to do what they think best. This has made specifying a universal device to control dimmable LED lighting challenging, however Theben has stepped up to the plate with its range of KNX dimmers.

The Universal Dimming Actuator DMG 2 T KNX is part of Theben’s successful MIX range of actuators and controllers for switching, dimming and heating control. The MIX range is a series of devices, consisting of a base unit and up to two extension modules make it easier and more cost-effective to control multiple channels.  Two, four or six channels of dimming can be configured per device group and there is also the option to add booster units (DMB 1 T) for higher loads.

The new Universal Dimming Actuators provide step less dimming using optimised dimming curves included in the KNX ETS configuration software, and new dimming curves can be imported via the ETS as they become available. The device has Scene Setting function, in the same way the  8-way MIX RMG 8 S KNX switching actuator.

A useful feature is that, at the time of installation, dimming can be manually tested using push buttons on the front of the device before the KNX bus is connected.

The new Theben dimmer, has already been successfully installed in a number of UK sites and been tested with many leading UK suppliers of LED lights. Theben’s VDE approved in house testing facilities test new lights as they become available. Theben are happy to check proposed lights before systems designers commit to a project, and lighting engineers are welcome to contact the English-speaking helpdesk at Theben AG.
