DALI bus dimmer with 12/24 Vdc power supply, it pro-
vides LED sources brightness control function. Dimming
can can be managed by using different types of comman
-
ds: KNX buttons or other local control devices. The device
is suitable for installation in flush-mounting wall boxes.

Description
The ekinex DALI 1-channel dimmer EK-GM2-DL allows
brightness control of dimmable LED sources by means of
several kinds of button. It can be connected by means of
KNX (TP) pushbutton connected to a DALI / KNX Gate-
way or via another command device, directly connected
to the dedicated input, selectable from a normally open
button, 0-10V analog input, 1-10V analog input and 10 kΩ
potentiometer. The device has an integrated DALI bus
communication modules voltage and requires a 12 or 24
Vdc auxiliary power supply.
