The Slim Line Dimming Fixture Controller. Retrofit or new construction, commercial office space or school classrooms, the Echoflex Slim Line Dimming Controller is a versatile wireless switching / dimming lighting control solution for all these applications. The Slim Line Dimming Controller is a component of Echoflex’s Smart Space solutions that delivers energy savings to facilities through integrated and distributed control solutions. The controller utilizes low power wireless radio technology to communicate with battery-free, wireless photo sensors, occupancy / vacancy sensors and wall switches. The Slim Line Controller is easily installed in the luminaire with little disruption and no extra wiring runs. Installation of the Slim Line Dimming Controller typically takes less than 1 hour, making it one of the most affordable solutions for retrofitting existing luminaires. Installation of the controller in the ballast/driver cavity of the fixture eliminates the need to access the lighting circuits in the plenum or ceiling space. The controller has a 0 to 10 V dimming output for direct connection to the low voltage dimming wires and the on board relay switches lighting circuits based on occupancy/vacancy detection or switch action.
