The CBU-ASR is a wireless lighting controller that is designed specifically for direct integration into lighting fixtures for commercial buildings. It provides two independent 0-10 VDC channels / control signals suitable for tunable white (applications or any implementation that requires advanced control.


The Casambi system can be used to control a single luminaire or a complete lighting control system in an intelligent mesh network.


Powered from an external 12-24 VDC Class 2 power supply, consuming just 30 mA, the CBU-ASR includes a low voltage (12-24 VDC) switched output that can be used to control an external relay or power pack. A sensor input is suitable for use with industry standard occupancy sensors and the CBU-ASR can propagate this signal on the wireless network to control nearby devices, or even large areas.


Its small size of just 2.2” x 1.2” x 0.7” (72.6mm x 30.0mm x 18.0mm) allows for easy integration directly into the lighting fixture or electrical junction box, thereby reducing installation costs. To enhance radio range in large buildings, the CBU-ASR may also be surface-mounted on the luminaire or junction box.


Installation costs are further reduced through the use of Casambi’s intuitive mobile device app that greatly simplifies system setup and configuration. The app is downloaded at no charge via the Apple App Store and Google Play Store.


The CBU-ASR is UL and cUL listed, plenum rated and FCC/ISED certified. It is available for quantity orders now.
