Compact 3U Lithium-Ion UPS

The Vertiv Liebert PSI5-3000SRT120LI is a 3000VA, 2700W line-interactive UPS with a lithium-ion battery. Its short-depth 3U rack/tower chassis fits two-post and wall-mount racks while delivering pure sinewave output at a 0.9 power factor. Programmable outlets and USB plus EPO ports provide local management and emergency shutdown capability.

Ideal for space-constrained racks.

Suited for network closets and edge sites that need high power density in a shallow rack footprint and benefit from batteries that last up to three times longer than VRLA alternatives. Not suited for sites that require input or output voltages outside the 75-146 VAC input window or the 100/110/115/120/125 VAC selectable output range.

Deciding spec: 120 V nominal input and output

This unit operates on a 120 V nominal supply with a 75-146 VAC input range and user-selectable output voltages of 100, 110, 115, 120 or 125 VAC. If your facility uses a different nominal voltage, this model will not match the electrical infrastructure.

Highlights

  • More usable power from a compact design with 0.9 output power factor
  • Lithium-ion batteries last up to three times longer than VRLA alternatives
  • depth chassis fits 2-post and wall-mount racks
  • Rack or tower orientation adapts to any installation space
  • Pure sinewave output protects sensitive equipment on battery power

Questions about this item

When do the lithium-ion batteries need replacing?

Lithium-ion batteries last up to three times longer than traditional VRLA batteries, reducing replacement frequency.

What limits continuous operation at full 2700W load?

The 0.9 output power factor and 3000VA rating cap usable power at 2700W; sustained loads beyond that will trip the unit.

How much heat and noise does the 3U short-depth chassis produce during all-day runtime?

The compact 3U short-depth design fits 2-post and wall-mount racks; pure sinewave output and wide 75-146VAC input window reduce battery cycling and fan activity.
