ERn Rack-Mount Control Enclosure

ERn Rack-Mount Control Enclosure

The center of a network infrastructure

The Unison ERn Rack-mount Control Enclosure was designed to perform one important task: support all of the capabilities of the Paradigm™ Lighting Control System. ERn is the center of a network infrastructure, with no need for external gear. Like most infrastructure equipment, the ERn series is designed to fit 19" equipment racks, and blend in with other equipment. Use the ERn in with your networking gear and power distribution. The enclosure features rear-access wiring terminals, pre-wired power input with included cord, and it includes a black-painted, front panel with a locking door. The ERn is also available in a compact wall-mounted version for installing directly to a surface.

You're protected . What happens if the power goes out? Peace of mind. ERn's PowerSupport  technology includes RideThru  functionality, powering your processor for at least ten seconds in the event of electrical-grid disruption. And if that's not enough - you can even specify an optional Redundant Power Supply  to take over without any interruption in service.


The ERn2 is engineered for compactness. At just 5U, ERn2 fits wherever you need it to. No other enclosure is so small. The ERn2 supports one Paradigm processor and one Station Power Module, plus optional Redundant Power Supply.


Planning on expanding the lighting control system in the future - adding more moving lights, LED displays, building-automation devices, or control stations? Start with the ERn4 enclosure, designed with room to expand, using just 8U. For higher-density control, the ERn4 supports two Paradigm processors and a single Station Power Module for each. Each Station Power Module supports 63 control stations and up to 1,640 feet (500 meters) in total cable runs. To cover even additional control distances, an optional repeater or dual repeater can replace a Paradigm processor and Station Power module to provide an additional 500-meter run. Long station bus runs can be executed using mid-span repeaters. Like the ERn2, the ERn4 accepts the optional Redundant Power Supply.
