CBU-A2D is a Bluetooth-controllable, Casambi-enabled two-channel 0-10V/DALI controller that offers versatile control for a wide range of LED drivers and lighting applications. It supports a universal input voltage range from 100 to 277 VAC, making it compatible with global mains power standards. The controller can manage one or two 0-10V controllable LED drivers, or it can operate a tunable white LED driver using its two 0-10V control interfaces. In addition, CBU-A2D can be configured into a DALI mode, allowing it to connect directly to a DALI LED driver or DALI sensor to support presence detection and daylight harvesting functionalities. The device is fully compatible with the Casambi app, available for free on Apple App Store and Google Play Store, and can be incorporated into a simple one-luminaire direct control setup or expanded into a full-featured lighting control system with up to 250 units automatically forming an intelligent mesh network.
The wireless range between two CBU-A2D units or between a unit and a smartphone can vary significantly depending on environmental conditions and the design of the surrounding structures. In open-air conditions, the typical range is approximately 200 feet, but metal or dense structures may reduce the effective range. Because each CBU-A2D unit functions as a repeater within Casambi’s mesh network, thorough testing is recommended to ensure all units can be reliably controlled from any point within the network coverage area. This functionality ensures robust communication and seamless operation of multi-luminaire systems.
The input specifications of CBU-A2D include a voltage range of 100-240 VAC for CE, UL, and CSA compliance, and 277 VAC for UL and CSA standards, with a frequency of 50-60 Hz and a maximum mains current of 35 mA. The device maintains a no-load standby power consumption of less than 0.5 W. The controller offers two output channels: Channel 1 supports 0-10V output up to 7 mA (sinking) and DALI output at 12 VDC up to 20 mA (sourcing), with a maximum of one driver and one sensor or push button connected. Channel 2 provides 0-10V output up to 7 mA (sinking) and relay control at 12 VDC with a maximum current of 100 mA (sourcing), supporting one driver. These output options allow precise control over multiple driver types and integration with presence and daylight sensors.
CBU-A2D operates across an ambient temperature range of -20°C to +45°C (-4°F to +113°F) and a maximum case temperature of 70°C (+158°F). It is designed for indoor use only, with a protection rating of IP20 and built-in Class II safety. The device accommodates solid and stranded wire sizes from 0.5 to 1.5 mm² (16-20 AWG) with a recommended strip length of 6-7 mm and tightening torque of 0.4 Nm (2.6 Lb-In). Its compact dimensions of 76.0 x 26.0 x 23.0 mm (3.0 x 1.0 x 0.9 inch) and lightweight design (40 g / 1.39 oz) allow easy integration within luminaires or junction boxes. The unit is certified with FCC ID 2ALA3-CBUA2D, IC 22496-CBUA2D, and UL E494741, ensuring compliance with safety and communication standards.
CBU-A2D combines wireless Casambi control with robust 0-10V and DALI interface flexibility, enabling both single and multi-channel LED driver management. Its seamless integration into Casambi mesh networks ensures scalable, intelligent lighting control while maintaining compatibility with a wide range of sensors and control devices. This versatile controller is ideal for modern lighting systems requiring flexible installation, precise dimming, RGB or tunable white control, and smart sensor integration.
