The CBU-ASD-LR is a wireless, long-range control module that enables seamless lighting control for any type of LED driver supporting 0–10V, 1–10V, or DALI dimming interfaces. Available in two configurations—analog 0–10V (and 1–10V) or digital standalone DALI—the unit provides flexible control options suitable for a wide range of commercial, architectural, and industrial lighting applications. The standalone DALI output allows the device to function as both a controller and a power supply, making it possible to connect directly to an LED driver with a DALI interface without requiring an external DALI power supply. This streamlined design minimizes wiring complexity and component count, allowing efficient implementation of multi-channel lighting systems with adjustable color output (RGB or RGBW) or tunable white color temperature (CCT).
Although it utilizes a DALI protocol, the CBU-ASD-LR does not conform to IEC 62386 standards and is not intended for integration into existing DALI networks. It operates exclusively within closed systems as part of self-contained lighting installations that do not connect to external DALI controllers. The unit communicates wirelessly through the Casambi ecosystem, using Bluetooth 5.0 technology to form a secure, self-organizing mesh network. Through the Casambi app—available free from the Apple App Store and Google Play—users can configure, control, and manage lighting systems across large networks of luminaires from any access point without requiring an external gateway. The system also supports standard on/off wall switch inputs, allowing manual dimming or control when needed.
The CBU-ASD-LR incorporates a variety of functional and configurational features that enhance flexibility and ease of use. It supports wireless control without external gateway devices and automatically creates a fast, stable Bluetooth mesh network among connected nodes. Its compact size allows easy integration into luminaires or electrical enclosures. The device provides configurable analog or digital output, enabling operation as a 0–10V sinking/sourcing interface or as a standalone DALI controller. It supports both RGB and tunable white configurations, as well as switched mains output control. Compatibility with standard wall switches and push-button inputs is available, and it can be configured to function with standard PIR sensors for occupancy-based smart switching. Over-the-air firmware updates ensure that the device remains compatible with evolving Casambi system capabilities, while Casambi’s cloud service enhances system performance and user experience.
In terms of electrical specifications, the CBU-ASD-LR operates at an input voltage of 220–240 VAC with a frequency of 50 Hz and a maximum mains current of 0.6 A. Its output relay functions on the phase line at the same voltage and frequency range, though the mains output must only be connected to an external relay—not directly to an LED driver mains input—to avoid fire risk. The analog 0–10V output operates within a 0–10 VDC voltage range and supports a maximum current of 6 mA. The standalone DALI output provides 9–12 VDC at up to 6 mA. The integrated Bluetooth radio transceiver operates in the 2402–2480 MHz frequency band with a maximum transmission power of +8 dBm.
The unit performs reliably across a wide range of environmental conditions. It supports ambient temperatures from -20°C to +50°C with output current derating starting from +40°C to +50°C, a maximum case temperature of +75°C, and storage temperatures between -25°C and +75°C. It also tolerates up to 80% non-condensing relative humidity. The terminal connectors accommodate both solid and stranded wires ranging from 0.5–1.5 mm² (14–22 AWG) with a strip length of 6–7 mm and a tightening torque of 0.4 Nm.
Mechanically, the CBU-ASD-LR is compact and lightweight, measuring 56.5 × 35.8 × 22.3 mm and weighing just 48 grams. It carries an IP20 protection rating, suitable for indoor applications only, and is classified under Protection Class II for electrical safety. Together, these specifications make the CBU-ASD-LR a versatile and space-efficient wireless control module that simplifies installation, enables robust Bluetooth mesh lighting management, and supports both analog and digital dimming configurations for modern, connected lighting environments.
