KNX 12/24/48 Vdc 4-channel dimmer

DIN-Rail mount modules

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

Description

The KNX 12/24/48 Vdc 4-channel dimmer EK-GD1-TP-4-LV allows PWM brightness control of LED loads. Designed specifically for dimmable LED strips and loads, it is compatible with the KNX system and is suitable for monochrome strips. Installation is simple via DIN-rail mounting, ensuring seamless integration into switch cabinets. The device has an integrated SELV 30 Vdc bus communication module, KNX certified.

Dimming
  • PWM dimming mode in the range 250 Hz to 6 kHz
  • Dimming range: 1-100%.
Delivery

A terminal for connection to the bus line is included in the scope of delivery.

Functions / Features
    • ON/OFF control and dimming of individual or grouped luminaires
    • Selection of PWM output frequency by ETS, from 250 Hz to 6 kHz
    • Parallel connection of outputs possible to increase output power
    • Fade on/off time, minimum and maximum brightness level, linear or logarithmic dimming curve settable via ETS
    • Soft or instantaneous switching on and off, with settable delay
    • Configuration of behaviour after power reset, bus ON/OFF, unloading via ETS
    • Channels can be set by ETS as independent, parallel or with copy function from another channel
    • Blocking function, forced operation, staircase light, scenes, night, counter and logic functions for each channel, settable from ETS
    • Alarm for power failure
    • Manual control with membrane buttons for local ON/OFF testing of channels 1-2-3-4: in manual mode, short press of a channel button activates/deactivates the load, pressing for at least 2 seconds causes the load to flash every 1 s approx.
    • Relay contact for switching off the AC/DC power supply when 12/24/48 Vdc outputs are switched off, or alternatively as relay for auxiliary output
    • Auxiliary output function via relay with status indication via KNX
