• Max per channel: 200 W (incandescent/halogen), 100 W (dimmable LED)
• Standby loss: 0.5 W
• Width: 4 modules (TE)
• Protection: overload and overtemperature
• Adjustable minimum brightness
• Operating temperature: -20 °C to +50 °C

Why choose it

Integrates with EnOcean-based wireless systems without additional gateways. The compact 4-module design saves space in distribution boards, and per-channel load limits allow flexible lighting configurations.

Ideal use cases

• Retrofitting existing buildings with wireless dimming control
• Controlling multiple lighting groups from a central electrical cabinet
• Integrating with EnOcean switches and sensors for automated lighting scenes

Good to know
