DALI 2 standard dimmers at 12 / 48 Vdc
with 1 / 2 - channels
Codes: EK-GD2-DL-1-LV, EK-GD2-DL-2-LV
DALI 2 bus dimmer with 12/48 Vdc voltage supply and 1
or 2 channels, with brightness of LED sources control and
dimmable in PWM modulation.
Description
The ekinex dimmers DALI 2 standard with 1 / 2-channels
EK-GD2-DL-1-LV and EK-GD2-DL-2-LV allow brightness
control of LED loads from 12 to 48 Vdc in constant volta-
ge, dimmable in PWM modulation.
• The 1 CH model is DALI DT6 only and equipped with a
local control device (N.O. button), connected directly to
the dedicated input, with stand-alone or status update
function on the DALI bus.
• the 2 CH model can be configured with a single DT6
output channel, 2 single DT6 channels or a single chan-
nel in TW DALI DT8 mode.
DT6 / DT8 setting for EK-GD2-DL-2-LV model is done via
local selector switch. The devices have an integrated bus
communication module DALI 2 certified.

Warning! Dimmers require the use of a power
supply in accordance with EN 61347-2-13, such
as the Mean Well mod. HLG-480H-24A.
Main functional characteristics
• Memory function configurable via DALI bus: it stores
the last brightness level, in case of power failure
• Soft switching on and off
• Brightness adjustment to full power off (dim-to-dark)
• Min. brightness level: 0.1% (1% with push for 1 CH)
• DALI-settable dimming curve: linear/logarithmic for
1CH, 2 CH, linear/quadratic/exponential for 4 CH
• On and off times settable via DALI
• Control inputs: N.O. push button (for EK-GD2-DL-1-LV
only), DALI
• Optimized output curve
• Button for mode change and / or DT6 / DT8 selection
(depending on the device version)
• Status LED (switch to stand-by after 1 min.)
i
Note: the 1-CH device factory default values are:
automatic detection of the local command set to
N.O. pushbutton and minimum dimming value set
to 1%.
