Light dimmer module EK-GD2-TP-2-LV

Description
The EK-GD2-TP-2-LV 2-channel KNX 12/24/48 Vdc dimmer allows brightness control in constant voltage (CV) PWM mode for LED loads. Specifically designed for dimmable LED strips and loads, it is compatible with the KNX system and ideal for monochromatic and CCT strips with dynamic white (Tunable White). The device has an integrated SELV 30 Vdc bus communication module and is KNX certified.

Technical data

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

Functions / Features

• Plastic casing
• Device for free installation in junction boxes or on walls
• Mounting on 35 mm profile rail (using the special bracket included)
• 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 can be set from ETS
• Soft or instant on/off, with adjustable 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
• Auxiliary output function via relay (external) with status indication via KNX
• Installer mode (with KNX bus active): pressing the programming button for about 2 seconds activates/deactivates the programming LED and load flashing approximately every 1 second

Configuration and commissioning
A detailed description of the parameters can be found in the device application manual. ETS5 or later versions are required for configuration and commissioning. Application program for ETS: APEKGDXTPXLVTW##.knxprod (## = version).
