US Patent 12004282 Hybrid dimming controller with multi-class outputs

A hybrid dimming controller for a lighting control system providing isolated class 1 and class 2 dimming outputs. The controller has two NEC class 1 outputs for providing independent low-voltage dimming-control signals for two lighting loads and two NEC class 2 outputs for providing the same two independent dimming control-signals for the lighting loads. Thus, the controller has both a class 1 and a class 2 outputs for delivering the same dimming-control signal for each of the two lighting loads while maintaining within the controller the isolation that is required between class 1 and class 2 circuits.
