Line-interactive 1500 VA / 1350 W UPS with automatic voltage regulation, pure sine-wave output, six NEMA 5-15R outlets, LCD status panel, included network management card and TAA compliance
Option PSI5-1500RT120TAAN
Struck-through versions exist but are not stocked here.
The Vertiv PSI5-1500RT120TAAN is a line-interactive UPS rated at 1500VA and 1350W for 120V environments. It uses automatic voltage regulation and a pure sine wave output on battery to protect connected equipment. The unit includes a network card for remote monitoring of up to 50 systems. It mounts in a tower or 2U rack form factor.
This UPS fits administrators who require UL 1778 listed protection with AVR and a 0.9 output power factor for active PFC power supplies. The included UNITY card enables centralised monitoring via Vertiv Trellis Power Insight. Buyers who need extended runtime at full load beyond six minutes or input voltage ranges outside 75 to 146 VAC should consider other models.
At full load the internal VRLA batteries provide six minutes of backup, rising to 18 minutes at half load. Recharge to 90 percent capacity takes four hours. This runtime figure is the primary constraint for sizing the UPS to your critical shutdown window.

Other versions of this model
Same family, different memory, cooler or clock — compare before you commit.
The unit ships with a NEMA 5-15 input cord, so a standard 120 V wall receptacle rated for 15 A is required.
Yes, the line-interactive topology with AVR corrects voltages across the full 75 to 146 VAC range without using battery power.
The LCD will show the card’s IP address once it acquires a DHCP lease, and the free Vertiv Trellis Power Insight application will list the UPS among up to 50 monitored units.
