Vertiv Liebert PSI5 1U Line Interactive UPS Rack Mount UPS from 1000VA to 1440VA

The Vertiv Liebert PSI5 1U line interactive rack mount uninterruptible power supply (UPS) is designed to protect and extend the life of your electronic devices in school, home and office. It offers cost-effective protection from downtime and damage caused by power outages, brownouts, sags, surges or noise interference.

Automatic Voltage Regulation (AVR) extends battery life and safeguards critical equipment. It ensures availability of critical IT applications such as network closets and small data centers. This battery backup allows orderly shutdown of critical equipment. Add an optional communication card and remotely monitor up to 50 UPS systems through the free Vertiv Trellis Power Insight Application. It has a 2-year Vertiv warranty with optional extensions for up to 5 years total coverage. This UPS includes:

-Compact 1U rack space for the same features as a 2U rack mount UPS

-Advanced, pure sine wave output power on battery

-0.9 power factor, which means more usable power for connected devices

-Voltage regulation from 83 to 159 VAC without using the battery

-Less than 6 milliseconds transfer time to battery

-LCD display panel, output overload, or low-battery or replace-battery warnings

-Options for communication card for remote monitoring of devices.


Downtime is costly. Ensure that your critical IT systems are protected from power issues. With advanced pure sine wave, the Vertiv Liebert PSI5 UPS compensates for power fluctuations, protects against equipment damage, and prevents data loss during a power disturbance. The AVR technology safeguards equipment against a range of utility power fluctuations without battery operation.


The Vertiv Liebert PSI5 1U rack mount UPS provides similar power, protection, and capabilities of the 2U UPS in a more compact 1U form-factor saving space in the rack. It is best for customer applications that have limited rack space and need a more compact rack UPS. Just add the optional network (SNMP) communication card and remotely monitor up to 50 UPS systems through the free Vertiv Trellis Power Insight Application.


Vertiv backs all Liebert PSI5 UPS systems with two-year, full unit coverage, including the battery. The Vertiv no-hassle, advanced replacement warranty covers all shipping fees and includes next-day delivery, which ensures customers will receive their replacement UPS prior to returning their damaged unit with no questions asked.

The cost-effective Vertiv Liebert PSI5 family safeguards investments during power anomalies. During an outage, the units allow key applications to continue to function until a safe shutdown can be performed.

With advanced pure sine wave power conditioning, the Vertiv Liebert PSI5 UPS protects valuable electronic equipment from the damage power fluctuations can cause. It’s ideal for media closet electronics, high-end gaming, home theater systems, smart home technology and more. The Vertiv Liebert PSI5 allows users to save their progress during power loss and safeguard expensive electronics when utility power fluctuates.

Power disturbances can disrupt the digital systems teachers and school administrators depend on. With the advanced power conditioning and backup power provided by the Vertiv Liebert PSI5 UPS, school districts can feel confident that their vital electronics are protected.
