Ekinex EK-GM2-DL Quick Start Manual

DALI 1-channel dimmer
Code: EK-GM2-DL
S
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.

Functional characteristics

• Constant voltage dimmer, 1 channel
• DALI bus command
• Local command: N.O. pushbutton / analog input 0-10V
/ 1-10V / 10 kΩ Potentiometer
• Analog automatic detection of the local command
• Brightness adjustment for LED loads
• Voltage output for R loads
• Typical efficiency > 95%
• Brightness adjustment up to full off (Dim to Dark)
• Brightness adjustment of white light or monochromatic
color
• Minimum value of dimming: 0.1% (1% Push)
• Memory function: it stores the last brightness level in
case of a power failure
• Possibility to set minimum dimming, Fade-in and Fade-
Out (Push menu)
• Optimized output curve
• Soft start and soft stop

Note: the factory default values are: automatic de-
tection of the local command set to N.O. pushbutton
and minimum dimming value set to 1%.
