The Eaton® Rack Power Module (RPM-3U/3Ui) is designed to distribute power within a rack. Providing
outstanding performance and reliability, the RPM-3U/3Ui's unique benefits include the following:
• Provides plug-and-play primary distribution from a three-phase UPS to secondary power distribution
devices. The RPM-3U/3Ui is ideal for enhancing the output distribution of UPSs such as the Eaton
BladeUPS®.
• Functions in a wide variety of applications supporting various data center loads at various voltages, power
cord configurations, and layouts.
• Can be installed in any standard 48-cm ( 9-inch) EIA rack or cabinet in 3U applications with included
hardware.
• Can be mounted on a wall with the optional wallmount brackets and customer-provided fasteners
appropriate for the type of wall.
• Organizes power distribution and simplifies cable management, making it easier to follow the power path
to the load. The RPM-3U/3Ui also improves load balancing, reducing nuisance overload alarms from the
UPS.
• Indicator LEDs that show when incoming power is available to the RPM-3U/3Ui and when an alarm is
present.
• Columns of LEDs labeled to match the output breaker poles and the input lines. Each column displays a
reading of load status.
• Circuit breakers and indicator LEDs located on the front panel for easy access.
• Plug-receptacle model that is customer-installable without the services of a licensed electrician, once the
main connection to the UPS is made.
• Backed by worldwide agency approvals.
