Dimmer Rack |
| Abstract: |
A dimmer rack for mounting a plurality of modular units called dimmer
modules is disclosed. Each of the modules is used to provide dimming
control for each lighting circuit in a lighting system. The rack is a
vertical enclosure and utilizes a plurality of modular shelving elements
attached to the sides of each file to define individual receptacles for
each module. Tabs in the shelving register with grovoes on the external
housing of the dimmer modules, whereby precise tongue and groove mounting
of each dimmer module is obtained. The rack provides vertical input power
and control signal busses which are mounted side by side at the rear of
the rack which register with and are engaged by first mating connectors on
the rear of each of the dimmer modules at one end therof. A vertical
output power bus is provided at the seat of the rack on the side opposite
the power and control signal busses which registers with and engages other
mating connectors on the rear of the dimmer modules at the end opposite
the first connectors. A vertical neutral bus strip is mounted adjacent the
output power bus to provide a return wire connection point for each
lighting circuit. Where three phase power is supplied to the rack, the
dimmer modules are grouped vertically by phase, one below the other. This
permits quick and efficient rack to rack bussing.
