550 VA rack-mount UPS for servers

The Eaton 5P550R is a 1U rack-mountable battery backup rated at 550 VA and 420 W. It accepts 120 V input through a NEMA 5-15P plug and provides five NEMA 5-15R outlets. RS-232 and USB ports support management software integration.

Suits small rack loads; not for larger power needs

This unit fits administrators protecting a few network switches, a security appliance or a single entry-level server in a 120 V environment. The adjustable input window of 70-153 Vac helps ride through unstable mains. Builders needing more than 420 W or additional outlet count should consider a higher-capacity model.

550 VA / 420 W rating determines load coverage

The volt-ampere and watt ratings define exactly how much equipment the UPS can support during an outage. Add the power draw of every device you plan to connect; if the total exceeds 420 W the unit will overload and shut down. Match the load to this figure before purchase.

Questions about this item

How often will the internal battery need to be replaced in the 5P550R?

The sealed lead-acid battery typically lasts three to five years; Eaton recommends replacement when runtime drops below your required threshold.

What is the first limit reached when the 5P550R runs at continuous 420 W load?

The 420 W real-power rating is the hard ceiling; exceeding it triggers overload shutdown even though the VA rating is 550.

How much heat and noise does the 5P550R produce during all-day operation?

In normal online mode the unit runs fan-cooled; audible airflow is present and the 1U chassis exhausts warm air into the rack aisle.
