CBU-DCS

CBU-DCS is a Bluetooth controllable, CASAMBI enabled DALI controller. CBU-DCS does not have its own power supply. Instead, it is powered directly from a DALI bus.
CBU-DCS can be used with a DALI sensor for presence detection or daylight harvesting, or it can be used for controlling DALI drivers that have an integrated DALI bus power supply.
