KNX dimmer 12/24/48 Vdc 4 channels - Tunable White

DIN-Rail mount modules

CODE: EK-GD1-TP-4-LV-T

Description

The EK-GD1-TP-4-LV-T 4-channel KNX 12/24/48 Vdc dimmer allows brightness control in PWM mode at constant voltage (CV) for LED loads. Designed specifically for dimmable LED strips and loads, it is compatible with the KNX system and ideal for monochromatic and CCT strips with dynamic white (TW). Installation is simple via DIN rail mounting, ensuring perfect integration into electrical panels. The device has an integrated SELV 30 Vdc bus communication module, KNX certified.

Dimming
  • PWM dimming mode in the range 250 Hz ÷ 6 kHZ
  • Dimming range: 1-100%
Supply

The supply includes a terminal for connection to the bus line.

Functions / Features
  • Plastic housing
  • Device for installation on 35 mm profile rail (4 modular units)
  • IP20 protection rating (device installed)
  • ON/OFF control and brightness adjustment of individual or grouped lighting fixtures, Tunable White and DimToWarm
  • Selection of PWM output frequency from ETS from 250 Hz to 6 kHz
  • Fade-in and fade-out time, minimum and maximum brightness level, linear or logarithmic adjustment curve settable from ETS
  • Soft or instant on/off, with settable delay
  • Possibility of parallel connection of outputs to increase output power
  • Configuration of behavior after power restoration, bus ON/OFF, download via ETS
  • Channels can be set from ETS as independent, parallel, or Tunable White
  • Lock function, forced operation, staircase light, scenarios, night mode, meter, and logic functions for each channel, settable from ETS
  • Power failure alarm
  • Manual control with membrane buttons for local ON/OFF testing of channels 1-2-3-4: in manual mode, briefly pressing the button for a channel activates/deactivates the load; pressing for at least 2 seconds causes the load to flash approximately every 1 second
  • Relay contact for switching off the AC/DC power supply when the 12/24/48 Vdc outputs are off, or alternatively as a relay for auxiliary output
  • Auxiliary output function via relay with status indication via KNX
