Edge IT power protection

The Vertiv Liebert PSI5 3000VA UPS safeguards critical servers and networking gear in edge and distributed IT applications. Its line-interactive design delivers pure sine wave output on battery and automatic voltage regulation to handle unstable mains supply. TAA compliance confirms manufacture in the US or a TAA-compliant country for regulated procurements.

Sustained-load runtime

At full 2700W load the lithium-ion battery provides up to 8.9 minutes of backup, giving time for graceful shutdown or generator start. At half load the runtime extends to 20 minutes, covering typical brown-out durations. Lithium-ion cells recharge faster and last up to three times longer than traditional VRLA batteries, reducing replacement cycles.

Input connection constraint

The unit requires a 120V L5-30P supply plug, so facilities without that receptacle cannot use it without electrical work. Output voltage is user selectable among 100, 110, 115, 120 or 125VAC to match local equipment needs. Buyers needing a different input plug or higher voltage input should look elsewhere.

Questions about this item

How loud is the PSI5-3000RT120LITAAN when it runs continuously in a rack?

The unit is a line-interactive UPS with automatic voltage regulation, so the internal fans only spin at higher speed when the load is heavy or the battery is charging; under typical office loads it stays quiet enough for a standard server room.

What input plug and circuit does the PSI5-3000RT120LITAAN need to operate?

It requires a NEMA L5-30P receptacle on a 120 V, 30 A branch circuit; the nominal input range is 75-146 VAC, so the building supply must stay within those limits.

Will the PSI5-3000RT120LITAAN work with my older 100 V or 115 V equipment?

Yes — the output voltage is user-selectable to 100, 110, 115, 120 or 125 VAC, so legacy gear rated for any of those voltages can be plugged into the six 5-20R or single L5-30R outlets.
