DALI Dimmer 12/48 Vdc 1-channel

DIN-Rail mount modules



The DALI-2 1-channel dimmer EK-GD2-DL-1-LV allows the brightness control of low voltage LED sources from 12 to 48Vdc by means of PWM dimming. DALI-2 bus input reference IEC 62386. Dynamic white temperature control TW DALI DT8, 2 independent channels (2 DALI addresses) or a single DALI DT6 channel. Functions can be set by means of a selector switch. Bus input DALI-2 reference IEC 62386.

Technical data
  • Device power supply: 10.8 Vdc (min)... 52.8 Vdc (max)
  • Max. power: 240W
  • Control: BUS DALI or local button

The graph shows the phenomenon of flickering as a function of frequency, measured over the entire dimming range. The results show the low risk zone (yellow) and the zone with no observable effect (green). Defined by IEEE 1789-20156.
