MDRC dimmer

Complex lighting control in presentation rooms and functional buildings.

Flexibility is needed to control the different requirements for large rooms or halls with several illumination groups.

The MDRCs for dimmers are part of a modular technology that makes it possible to control and dim different rooms from the distribution box. Depending on requirement, the light from the distribution box can be controlled via a control element or in the room via an extension unit.
A central control in restaurants and hotels is practical, for example, since the lights can be switched on and off from a central location during operating periods.

There is almost nothing that the Busch-Dimmer® units do not offer, because their intelligent concept is unique.
Just one example: Prefabricated cables connect dimmers and power modules. And the different modules can be latched onto the central control unit without the need of a tool. Because the covering cap of the dimmer can be replaced with push-on modules. You can choose between a tapping control element, a rotary control element, and a timer control element. For convenient, central control. The decentralized button or rotary control elements can also be blocked with the use of the timer module.

The allocation of lamps and dimmers in the options list for a lamp suitable for the dimmer (and vice versa) is to point out compatible combinations of lamps and dimmers.  additional information


Modular technology.

Power modules in the modular system also provide the option of dimming large loads. Up to six power modules can be connected to a dimmer in the distribution box. This enables loads up to 3,020 W/VA to be controlled via a single lamp wire. And it is operated when necessary the same as with any other dimmer, simply via rotary or touch-dimmer since the power modules remain out of sight in the distribution box and there ensure the correct function. An enormous advantage: During renovations, for example, no additional cables need to be installed.
