DALI MCU: Digital potentiometer with DALI
Manual lighting control with the DALI MCU for rooms with grouped luminaires with
as many as 50 ECG, with or without dividing wall
1. Application
Consider you want to switch on/off and dim the light
in a room, a restaurant or bar, a foyer or lounge etc
- but you want to do it from either of its two doors,
no matter which. For this to work, the two control
points would have to operate synchronously in such
a fashion that the lighting system responds
immediately and harmoniously when the brightness
level is changed at either of the control devices.
With the DALI MCU digital potentiometer, it is easy
to meet such requirements.

The parallel connection between the two devices
(control points), which would be required for our
example to work, becomes super simple - and it
does not necessitate any demanding installations
and/or additional control components.
Each control circuit simultaneously affords the
integration of as many as 50 luminaires and of up to
4 DALI MCU control devices (control points). And all
that while allowing for the required comfortable,
easy and complete control over the lighting levels at
any time.
