Vertiv PSI5 1U Rack UPS
The Vertiv PSI5-1500RM1201U is a new line-interactive UPS in a 1U rack enclosure. It delivers 1440VA and 1350W at 120V with a 0.9 power factor and automatic voltage regulation. Five NEMA 5-15R outlets are provided, two of which are programmable. A USB HID port and an EPO port are included for management and emergency shutdown.
Suited for 120V rack environments
This UPS suits server rooms and network closets that operate on 120V utility power and need pure sine-wave output on battery. It fits a single rack unit and accepts a NEMA 5-15P plug. It is not for sites that require 100V, 110V, 115V or 125V nominal input without reconfiguration. It is not for installations that need a serial port or an integrated network management card. It is not for loads exceeding 1350W.
1350W output at 0.9 power factor
The 1350W rating at 0.9 power factor is the figure that determines whether connected equipment can be supported. VA rating is 1440VA. Battery recharge reaches 90 percent capacity in six hours. Surge protection meets ANSI C62.41 Category A Level 3 at 1372 J. Operating temperature range is 32 to 104 °F.

In stockQuestions about this item
Will the 1U rack height and NEMA 5-15P input let me keep using my existing 120V rack PDU?
The unit fits a standard 1U space and plugs into a NEMA 5-15P receptacle so it connects directly to most 120V rack PDUs without adapters.
How can I confirm the pure sine wave output is active when the UPS switches to battery?
The front LCD shows real-time output waveform status and the USB HID port reports battery-mode operation to monitoring software.
Which cables and accessories ship with the PSI5-1500RM1201U and what must I source separately?
The box includes the UPS, rack-mount brackets, USB cable and documentation; network management cards and additional battery packs are sold separately.
