Purpose & Audience

The Vertiv PSI5-800RT120 is a line-interactive UPS rated at 800VA and 720W with a 0.9 power factor. It delivers pure sine wave output on battery and includes automatic voltage regulation across a 75-146VAC input window. The unit suits network closets, edge sites, workstations and gaming systems that need orderly shutdown during outages.

Deciding Specification

The critical figure is the 720W real-power rating; connected equipment must not exceed this load. Six NEMA 5-15R receptacles are provided, with one programmable outlet group for load shedding. Input connects via a NEMA 5-15 plug and the output voltage can be set to 100, 110, 115, 120 or 125VAC.

Thermals, Noise & Power

Operating temperature range is 32-104°F (0-40°C) and the unit meets UL 1778 safety standards. A rotating LCD panel reports status in both tower and 2U rack orientations. The VRLA battery pack recharges to 90 percent in four hours and is user-replaceable using the PSI5-24VBATT kit.

Questions about this item

How much real power does the 800VA rating deliver to my equipment?

The unit supplies up to 720 watts at a 0.9 power factor, so active-PFC power supplies and other loads can draw their full rated wattage within that limit.

What input plug and voltage window does the UPS accept?

It connects via a NEMA 5-15 plug and operates from 75 to 146 VAC at 55 to 65 Hz, automatically regulating voltage without using battery power.

What physical space and weight should I plan for when mounting it?

The 2U rack/tower chassis weighs about 28.40 lb and fits a standard 2U rack opening; the rotating LCD lets you read the display in either orientation.
