Zusammenfassung: | 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.
单通道数字可寻址照明接口(DALI)系统能够包含专用外部电源,其工作在恒定电压/恒定电流模式中以满足DALI总线的要求。照明控制器从DALI总线来供电。在发明主题的个实施例中,提供种照明系统,其包含两个或多个控制(例如DALI)总线和多通道电源,其能够用于以恒定电压向系统的控制器供电,并且以单独和恒定电流向单独控制总线供电。为了保护控制器和总线免受由误连线或其他错误条件所引起的过载,提供种保护电路组合件。 |
