Abstract
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.
Claims5
A dimming controller for a lighting load comprising:
- a class 1 output operable to provide a class 1 dimmer signal contained within a first conduit;
- a class 2 power output isolated from the class 1 contained within a second conduit, the class 2 output operable to provide a class 2 dimmer signal;
- a first low voltage connector and a second low voltage connector, the first low voltage connector operable to receive and output the class 1 dimmer signal for the first lightning load and the second low voltage connector operable to receive and output the class 2 dimmer signal for the second lightning load;
- a first output wire operably connected to the class 1 and class 2 outputs and operable to transmit the class 2 dimmer signal to a lighting load;
- and
- a second output wire operably connected to the class 1 and class 2 outputs and operable to transmit the class 1 dimmer signal to a lightning load;
- wherein, through the low voltage connector, the dimming controller can provide two independent control signals for independent dimming control of the first and second lightning loads.
