Abstract
A self contained multiple dimming channel package includes a housing with a main power circuit board supported on its bottom wall and a control circuit board extending laterally and vertically to baffle air flow through the housing. A cross flow cooling fan forces air through an opening in the control board and across power switching modules and toroidal chokes mounted to the main board. Each power switching module includes a heat sink with fins parallel to the air flow, and the chokes are mounted in rows with their central openings aligned with the air flow. The power switching modules include circuits attached to the heat sinks with terminals releasably plugged into mating connectors on the main board. Circuit breaker switches are snapped into place in the housing. The front corners of the housing are provided with integral mounting bracket and handle members.
