Abstract
A plug-in dimmer module for providing controlled power to one or more lighting fixtures or groups of fixtures. The dimmer module includes a housing with one or more circuit breakers located at one end, a power device with one or more dimmer circuits located at an opposite end, and one or more toroidal chokes located in a middle section. The power device includes built-in contacts for output power to the lighting fixture(s) and for control and sensor signals, and the dimmer module is adapted to plug directly into a slot in a rack, to engage the contacts. The components of the dimmer module are laid out efficiently within the housing, with minimal wastage of space and without the need for extraneous electrical conductors.
