A full rack consists of 48 dimmer module slots,
each capable of delivering power and control contacts for quad, dual or single
dimmers of 2.4kw and 6.0kw capacity. Each module utilizes the PRECIZPIN plug-in
system. This self aligning contact is designed to provide uniform and
consistent pressure between dimmer pins and rack receptacles to prevent
deterioration and overheating of the electrical contacts. Pins are rated at 125
amperes.
Each dimmer cabinet is supplies with all
required plug-in firing cards, controller card and power supply card. The
firing card is designed to regulate the output of each dimmer. Individual
feedback signals to each dimmer prevent any undesirable change of light output
due to line voltage fluctuations or line distortions. Each card controls up to
48 dimmer circuits using highly integrated circuit designs. A maximum of firing
cards (192 dimmer circuits per rack) are housed in the cabinet.
One controller card is provided to receive both
AMX-192 and DMX-512 data transmission protocols. The controller card contains a
built-in, non-volatile "patch" which allows random and non-sequential
dimmer numbering independent of dimmer ratings or placement in the rack.
One power supply card is supplied to provide the
necessary control voltages for proper operation and voltage feedback to the
firing cards.
A speed selectable low noise blower provides
forced air ventilation so that each dimmer is individually cooled with ambient
air. An ambient temperature of up to 40 degrees C. is accepted without
affecting operation of a fully loaded and operating rack. Temperature and air
sensors are an integral part of the protection system.
The dimmer rack has integral "amp
trap" protection against overcurrent and short circuit conditions on the
input main buss. The rack is complete with output and neutral connection
terminals, main busses and necessary control terminals. All connection points
are identified with permanently affixed markers. Each rack is equipped with
removable top and bottom cover plates to ease conduit installation on job
site.
