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

Description
The EK-GD2-TP-2-LV-M is a KNX 2-fold dimmer for LED loads, providing PWM brightness control optimized for dimmable and monochromatic LED strips. It integrates a SELV 30 Vdc KNX communication module and is KNX certified. The device is intended for DIN-rail or flush-mounted installation and supports parallel connection of outputs to increase total output power.
