Abstract
In a theater lighting system that regulates the luminescence of incandescent lamps, a main power unit is constructed of unitized components which include a chassis, main power apparatus drawers, electronic control circuit boards, a power bus unit and equipment rack. The drawers and boards are removably located in separate sections of the equipment cabinet remote from each other. The operator's console contains a plurality of sources of control signals which are supplied to the equipment cabinet to control the output power of main power apparatus. Main power apparatus of different power ratings are interchangably usable in each such system.

A main power unit for use in a theater lighting system which regulates the luminescence of incandescent lamps, comprising:
- a chassis having a first section and a second section remote from said first section;
- a plurality of substantially parallel bus bars positioned within said chassis and adjacent said first section and secured to said chassis, each said bus bar being conductively connected to an external source of main power and having a plurality of spaced apart main power connectors positioned along their lengths to form a matrix of bus bar connection sites;
- a plurality of drawers slidably and removable positioned in said first section of said chassis and grouped in rows to correspond with said bus bar connection sites, each of said drawers having a main power apparatus positioned therein, a drawer input connector conductively connected to said main power apparatus for connection with a said main power connector, a drawer output connector conductively connected to said main power apparatus, and a control signal input connector conductively connected to said main power apparatus;
- equipment rack means having a plurality of substantially parallel support members secured to said chassis and positioned within said first section of said chassis to support said drawers, each said support member having control connectors positioned along their lengths to correspond with and connect to said control signal input connectors of said drawers;
- a plurality of output means conductively connected to said drawer output connectors and to said incandescent lamps;
- and
- a plurality of control circuits positioned in said second section of said chassis, each of said circuits being conductively connected to receive control signals from an external source and to supply control signals to said support member control connectors.
