Light dimmer module EK-GD1-TP-4-LV-M

Product overview
The KNX 4-channel PWM dimmer EK-GD1-TP-4-LV provides PWM brightness control for monochrome LED strips and other compatible LED loads. Designed for integration into KNX building automation systems, it mounts on a 4-module DIN rail and includes an integrated SELV 30 Vdc bus communication module. The device is KNX certified and intended for use in electrical switch cabinets.
