The new CHROMOFLEX Casambi LED controller is a professional interface for commissioning and controlling complex LED lighting systems. Programming and operation of the CHROMOFLEX Casambi can be implemented directly via the user-friendly user interface of the Casambi app on the smartphone or tablet. For example, individual luminaires can be intuitively preset or conveniently combined to form a group using customisable icons. The maximum power of the CHROMOFLEX Casambi 4 channel control unit is 384 W. Each channel has an operating voltage of up to 4 A with 24 V, and 2 A in 48 V operation. In addition, four freely assignable inputs enable the connection of conventional push buttons. This enables users to also control scenes and colour sequences of individual LED luminaires or of several LED light sources grouped together in groups, in the conventional way.
