Edge UPS with lithium-ion batteries

The Vertiv Liebert PSI5 1500 VA UPS uses lithium-ion cells that last up to three times longer than traditional VRLA batteries. It delivers 1350 watts of pure sine-wave output to protect servers and network gear in distributed IT environments. TAA compliance confirms manufacture in the US or a TAA-approved country.

Suited for rack or tower edge deployments

This unit fits administrators who need extended battery life, lower total cost of ownership and remote management capability in a compact line-interactive design. Buyers who require longer runtime than 7.5 minutes at full load or 17.7 minutes at half load should consider other solutions.

Input voltage window 75 to 146 VAC

The UPS accepts a wide nominal 120 VAC range from 75 to 146 volts, allowing it to stay on utility power through sags and swells without draining the battery. User-selectable output voltages of 100, 110, 115, 120 and 125 VAC match local equipment requirements.

Questions about this item

Should I choose the 1500 VA / 1350 W model or a lower-capacity unit?

Select this 1500 VA model when your connected load approaches 1350 W; a smaller unit would only be appropriate if your total draw stays well below that figure.

What does the 1350 W rating mean once the UPS is installed?

It is the maximum real power the unit can deliver continuously; at that full load the lithium-ion battery provides up to 7.5 minutes of runtime, extending to 17.7 minutes at half load.

What does the 5-15P input and 5-15R outlets cap in practice?

The 5-15P plug limits input to a standard 120 V 15 A circuit, while the six 5-15R outlets share the UPS's 1350 W / 1500 VA total output capacity.
