Product Identity

The Vertiv PSI5-1500MT120LIN is a line-interactive UPS rated at 1500VA and 1350W with a .9 output power factor. It uses lithium-ion batteries and provides six NEMA 5-15R outlets for connected equipment. A USB interface and an included network card enable management and monitoring. The unit operates on 120VAC default input with user-selectable voltage options.

Suitability

This UPS suits workstations, networking gear and small servers that require battery backup with a compact tower footprint. Lithium-ion chemistry offers longer service life and faster recharge than traditional lead-acid designs. Buyers who need extended runtime at full load beyond 7.5 minutes or who require additional outlet count should look at higher-capacity or extended-battery models.

Pre-Installation Checks

Verify that your equipment plugs match NEMA 5-15R receptacles and that total connected load does not exceed 1350W. Confirm the installation site stays within the 0 to 40°C operating range and 20 to 90 percent non-condensing humidity. Ensure a NEMA 5-15P wall outlet is available for the 90-degree input plug and that clearance fits the 8.66 by 6.22 by 15.62 inch dimensions.

Questions about this item

What input plug must my wall outlet accept for the NEMA 5-15P connection?

The UPS ships with a NEMA 5-15P 90-degree plug, so the wall outlet must be a standard 120 V NEMA 5-15R receptacle.

Will my existing NEMA 5-15R power strips plug directly into the six outlets on this unit?

Yes, the six rear outlets are NEMA 5-15R, so any 5-15P cord or power strip connects without adapters.

How can I confirm the UPS is communicating with my management software after connecting the USB port?

The USB interface appears as a HID UPS device; your software should show battery status, load percentage and input voltage within seconds of plugging it in.
