What this UPS delivers

The Vertiv PSI5-5000RT208 is a line-interactive UPS rated at 5000 VA and 3825 W with a 208 V AC input and output. It fits a 2U rack or tower footprint and provides four NEMA L6-30R outlets for connected equipment. The unit is suited for server rooms and network closets that require battery backup with hot-swappable modules and an LCD status display.

Installation checks

Verify that your facility supplies 208 V AC through a NEMA L6-30P plug and that the input voltage stays within the 150-281 VAC range. Confirm the rack or tower space can accommodate a 2U high unit measuring 3.5 by 17.2 by 24.8 inches and weighing 87.7 lbs. Ensure the operating environment remains between 32 and 104 °F with humidity from 20 to 90 percent non-condensing.

Sustained-load behaviour

At full load the battery provides 3.0 minutes of run time, extending to 10.0 minutes at half load. After a discharge the internal VRLA batteries recharge to 90 percent capacity in four hours. Surge protection is rated at 2064 joules and the unit carries UL 1778 and c-UL-us listings for continuous operation.
