Casambi CBU-A2D Bluetooth Controller Wireless and Smart
CBU-A2D is a Bluetooth controllable, Casambi enabled 2 channel 0-10V/DALI controller. CBU-A2D has a universal 100-277 VAC input voltage range.
CBU-A2D can control one or two 0-10V controllable LED drivers, or it can control a tuneable white LED driver with two 0-10V control interfaces. The product can also be configured into a DALI mode where it can be connected to a DALI LED driver or DALI sensor for the presence and/or daylight harvesting functions.

What is Casambi?
Casambi solution is based on Bluetooth Low Energy, the state-of-the-art wireless technology and the only low power wireless technology in all modern smartphones and tablets, making it the only mainstream and future-proof low power radio technology in the world.
Bluetooth Low Energy was developed at Nokia Research Center where the founders of Casambi worked. That’s why Casambi has had the unique advantage in realizing the potential of Bluetooth Low Energy early on. Casambi started the development of the solution before there were any Bluetooth Low Energy devices on the market.
Wireless Mesh Network
On top of Bluetooth Low Energy, the Casambi technology provides a mesh network where all the intelligence of the system is replicated in every node and, in such a way, creates a system with no single points of failure.
Such self-organizing wireless mesh network can control a large number of fixtures from any point. It also allows for firmware updates over the network, allowing any kind of changes to be made over-the-air. In this kind of fully distributed and symmetric architecture, any unit can go offline and catch up from others when they return back online.
The Casambi devices are smart on their own and only connected when needed. An Internet connection is not necessary for normal operation, it is just needed for user interface configurations to be sent or recalled from the cloud service.
The Casambi app works as one of the user interfaces in a Casambi lighting control solution, as the commissioning tool and as well as a remote gateway. The Casambi app works with iOS as well as Android devices, like smartphones and tablets. The app is free to download by any end-user.
The Casambi app is made by user interface experts and in a way, that anyone – regardless of technical proficiency – can use it. The Casambi lighting control technology gives a possibility for Casambi’s partners to implement and develop anything needed for a full-featured lighting control system, but the Casambi app only shows in the user interface the functionality that is relevant to that particular installation. Therefore, the Casambi app is equally well suitable for the professional lighting market as well as the residential field.
