Light dimmer module EK-GD1-TP-4-HV-N

Description
The EK-GD1-TP-4-HV-N is a KNX bus device providing a 4-channel phase-cut dimmer for mains-voltage lighting loads. Designed for integration in KNX building and home automation systems, it simplifies load connections while offering flexible dimming and control options.

Technical data
Inputs

• Supply voltage: 90–230 Vac, 50/60 Hz
• Max. input current: 2 A

Outputs

• Supply voltage: 90–230 Vac, 50/60 Hz
• Output power per channel: 110 W @110 Vac; 220 W @220 Vac; 230 W @230 Vac
• Minimum load power: 1 W per channel
• Maximum current per output: 1 A per channel
• Maximum total current: 2 A
• Terminals: screw terminals (max. 4 mm2)

Dimming

• Dimming modes: Trailing Edge, Leading Edge (selectable via ETS) and AI Edge (optimised for 230 Vac LED strips)
• Dimming range: 1–100%

Notes
Compatible loads include incandescent lamps, mains-voltage halogen, dimmable mains-voltage LED lamps and LED strips, and switching power supplies designed for phase-cut dimming. In trailing edge mode the dimmer performs phase-cut at the trailing edge.
