Abstract
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.
