Summary:Single channel digital addressable lighting interface (DALI) systems can include a dedicated external power supply that operates in a constant voltage/constant current mode to meet requirements of the DALI bus. A lighting controller is powered from the DALI bus. In one embodiment of the inventive subject matter, a lighting system is provided that includes two or more control (e.g., DALI) buses and a multichannel power supply that can be used for powering a controller of the system with constant voltage and to power separate control buses with separate and constant current. In order to protect the controller and buses from overloads caused by miswiring or other erroneous conditions, a protection circuit assembly is provided. Los sistemas de interfaz de iluminación localizable digital de canal único (DALI) pueden incluir una fuente de energía externa dedicada que opera en un modo de corriente constante/voltaje constante para satisfacer los requerimientos del bus DALI; un controlador de iluminación se energiza desde el bus DAU; en una modalidad de la materia objeto inventiva, se proporciona un sistema de iluminación que incluye dos o más buses de control (por ejemplo, DALI) y una fuente de energía multicanal que se puede usar para energizar un controlador del sistema con voltaje constante y para energizar buses de control separados con corriente constante y separada; para proteger el controlador y los buses de control de sobrecargas causadas por cablear erróneamente u otras condiciones erróneas, se proporciona un ensamblaje del circuito de protección.
