Abstract
A high density dimmer module controls four separate lighting circuits and provides adequate cooling while maintaining a form factor identical to conventional dimmer modules. The module includes circuit breakers arranged in stacks located adjacent to the front of the module. The circuit breaker stacks are spaced apart to allow cooling air to flow between, and to each side of, the circuit breakers. The air then flows past a power device and four toroidal inductors which are arranged behind and between the stacks. In a preferred embodiment, the module includes an input power connector positioned adjacent the rear periphery of the module chassis, first and second stacks of circuit breakers positioned adjacent the front periphery, four inductors arranged in an arcuate pattern behind the circuit breaker stacks, a power device located adjacent a sidewall of the chassis, and four output load connectors positioned adjacent the rear periphery. The circuit breaker stacks are spaced apart to allow air entering the module at the front periphery to flow between the first inductor and the first and second circuit breaker stacks, past the seconds, thirds, and fourth inductors, and out of the modul…
