The ETC TR20AF Sensor3 Series ThruPower Module provides highly reliable dimming with remote activated mechanical relays and ThruPower bypass. The result is the foundation of a completely flexible power system design for your future lighting needs.
Sensor3 all-in-one ThruPower modules allow free mixing of dimming, switching, or manual bypass on a circuit by circuit basis without replacing the hardware in your Sensor power system. A local override completely bypasses the control system to guarantee that the unsuspecting board operator does not dim your intelligent lighting source. In bypass mode, the integral relay will eliminate the choke and SSR power cube thereby providing clean power to critical power supplies and lighting devices.
The ThruPower module supports circuit-specific setup and load feedback that can be accessed remotely with any ACN control system.
Where load type is not likely to be known at time of installation
Where production environment load types are likely to change frequently
Where your moving lights, LED, scroller, or power supplies warranty depends on constant power
