1500VA TAA-compliant UPS

The Vertiv PSI5-1500RT120TAA is a line-interactive battery backup rated at 1500VA and 1350W with a .9 power factor. It accepts 120V input through a NEMA 5-15 plug and provides six NEMA 5-15R outlets. The rotatable LCD monitor simplifies status checks in tower or rack orientation.

Pure sine wave on battery with AVR

Automatic voltage regulation corrects sags and swells between 75 and 146 VAC without using battery capacity. When the supply fails, the inverter delivers a pure sine wave output to protect sensitive loads. At full load the VRLA batteries sustain operation for 6 minutes; at half load the runtime extends to 18 minutes. Recharge to 90 percent takes 4 hours.

Hot-swappable batteries replace aging cells

The internal VRLA pack is rated for a 5-year life and can be swapped without powering down connected equipment. This unit replaces smaller VA backups that lack AVR or pure sine wave output, and it upgrades installations that need network management via the RJ-45 port. It is not suited for loads exceeding 1350W or for environments outside 32 to 104°F operating temperature.

Questions about this item

How much heat does the 1500VA UPS add to a rack that operates continuously at full load?

At full load the unit draws 1350W and its operating temperature range is 32° to 104°F, so the waste heat stays within that envelope; the rotatable LCD lets you monitor internal temperature without opening the rack.

What input plug and outlet types must already be present in the rack or wall circuit for this UPS to work?

The UPS connects with a NEMA 5-15 input plug and provides six NEMA 5-15R outlets, so the site needs a standard 120V 15A receptacle and matching cords for the protected equipment.

Will the USB and network management card work with older servers that only have serial or PS/2 management ports?

This model includes USB and an RJ-45 network port but no serial or PS/2 ports, so legacy servers would need a USB-to-serial adapter or network-based management software to communicate with the UPS.
