DRd Rack Components
Unison DRd racks are available in 6 or 12 module enclosures and are available for an input
voltage range of 85-300 VAC, 47-63 Hz. Racks are pre-wired and supplied with three
phase, 4 wire and ground, main lugs which are easily converted for split phase, 3 wire and
ground, operation without the need for additional materials.
DRd racks are available in 12, 24 and 48 circuit configurations.
N o t e :
In 48-circuit configurations, two DRd12-24 rack enclosures are cross-bussed to an
AX12X series main lug or main circuit breaker auxiliary rack enclosure. A single
Architectural Control Processor (SmartLink ACP or Paradigm ACP) provides
control for both racks.
DRd rack enclosures are supplied pre-wired for the specified voltage for your installation.
All rack enclosures operate at specified voltages within a frequency range of 47-63 Hz.
Phases within the rack enclosure may be bused together provided the maximum supplied
current does not exceed that of a three phase connection.
