摘要:
Systems and methods are disclosed that facilitate switching a lamp ballast between DALI and analog control states as a function of control state information stored prior to the ballast being powered of and control information received by an interface circuit for the ballast circuit. A depolarization circuit is coupled to the interface circuit and ensures consistent polarity across a rectifier circuit regardless of the polarity of two control wires coupled to a miswiring protection circuit in the interface circuit. In this manner, a single interface circuit provides dual 0-10V analog and DALI control for dimming a lighting device regardless of whether a wall-mounted controller coupled to the interface circuit is an analog or a DALI type controller, thereby mitigating a need to switch out a ballast circuit coupled to the lighting device when changing between DALI and analog type controllers.
