Light dimmer module EK-GC1-TP

Product description
The Ekinex EK-GC1-TP is a 4-channel RGBW LED dimmer designed for independent regulation of four constant-voltage LED strips (12/24 Vdc) or combined intensity and colour control of an RGB or RGBW LED strip. Colour selection is available in HSV or RGB mode. The unit is intended for installation on a 35 mm DIN-rail and integrates KNX bus communication for building automation. The device is bus-powered for control and requires an additional 12–30 Vdc supply for the controlled loads.

Technical data

• Strip supply voltage: max 30 Vdc, total max 16 A
• Control power: supplied via KNX bus (30 Vdc)
• Number of outputs: 4
• Maximum load current per channel: 4 A

Delivery
Delivery includes a KNX terminal block for bus connection and a terminal block for outputs and power supply.
