ETC Unison DRd Dimming Rack Enclosure - Manual (Page 7)

Introduction 3
Overview
Unison DRd enclosures are available in 6 or 12 module enclosures and are available for an
input voltage range of 85-300 V AC, 47-63 Hz. Enclosures 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 enclosures are available in 12, 24 and 48 circuit configurations.
DRd enclosures are supplied pre-wired for the specified voltage for your installation. All
enclosures operate at specified voltages within a frequency range of 47-63 Hz. Phases
within the enclosure may be bused together provided the maximum supplied current does
not exceed that of a three phase connection.

• Supports universal dimmer modules, fluorescent dimmer modules, constant circuit
breaker modules, relay modules, and reverse phase dimmer modules. Reference
“Modules Specification” , page 57 for a complete list of compatible modules.
• The DRd is controlled from either the Echo ® Architectural Control Processor
(E-ACP), SmartLink
®
Architectural Control Processor (S-ACP) or the Paradigm™
Architectural Control Processor (P-ACP).
N o t e : In 48-circuit configurations, two DRd12-24 enclosures are cross-bussed to an
AX12X series main lug or main circuit breaker auxiliary enclosure. A single
Architectural Control Processor (Echo, Paradigm, or SmartLink ACP) provides
control for both enclosures.
