depth rack UPS for dense IT spaces

The Vertiv PSI5-800SRT2ULIN is a new 800 VA 720 Watt lithium-ion battery backup built for 2U rack or tower deployment. It accepts 75-146 VAC input and delivers 120 VAC through six NEMA 5-15R outlets. The unit weighs 29.00 lbs and ships with rack ears, a flush-mount kit, a tower support base, a 2.4 meter input cord and a 1.8 meter USB cable.

720 Watt output capacity

The single figure that determines fit is the 720 Watt real-power rating. Connected equipment must not exceed this limit or the UPS will overload. The 800 VA apparent-power rating and 120 VAC output voltage are fixed, so sizing is a direct comparison between load watts and the 720 Watt maximum.

Rack or tower flexibility with network management

The included hardware lets the unit mount in a two-post rack using the flush-mount kit or stand as a tower on the supplied base. A network management card slot is present for remote monitoring via Vertiv Power Insight software. USB connectivity enables local management with Vertiv Power Assist. The package contains no additional batteries or extended-run modules.

Questions about this item

How does the 720-watt output translate to real-world runtime for my equipment?

The 720-watt rating is the maximum continuous power the UPS can deliver. Actual runtime depends on the total load you connect; a lower load will run longer on the internal lithium-ion battery.

What does the 75-146 VAC input range mean for my 120-volt supply?

The unit accepts incoming voltage from 75 to 146 volts. Within that window it corrects sags and swells without using battery power, preserving battery life for true outages.

What hardware is included to mount this 2U unit in a two-post rack?

The package includes rack-mount ears and a two-post rack mounting kit rated for 800-1500 VA models, plus a support base if you prefer tower orientation.
