CBU-ASD-LR is a wireless, long-range control unit for any type of driver with 0-10V, 1-10V or DALI dimming interface. The CBU-ASD-LR is available with either analog 0-10V (and 1-10V) or digital standalone DALI control interface.

With standalone DALI [1] output, CBU-ASD-LR acts both as a controller and power supply, making it possible to connect directly to an LED driver with DALI interface without needing an external DALI power supply. This so-called standalone DALI makes it possible to implement multi-channel lighting systems with adjustable color (RGB and RGBW) or color temperature (CCT), while keeping the wiring and number of components to a minimum.

The CBU-ASD-LR is controlled wirelessly with Casambi smartphone and tablet applications using Bluetooth 5.0 protocol. The Casambi App can be downloaded free of charge from Apple App Store and Google Play Store.



[1] The CBU-ASD-LR does not comply with IEC 62386 and therefore is not designed to be connected to an existing DALI network. The module can be used only in a closed system, i.e. as a part of a lighting system which is not connected to an external DALI network.
