Benefits
-
500VA – 3000VA
Wide range of available sizes to allow you to select the capacity and runtime that best meet your needs.
-
Optimized form factors
Multiple form factors to suit all site requirements, including tower, 2U and 3U Rack/Tower convertible form factors to provide flexibility at sites with variable installation needs.
-
Lithium-ion batteries
Vertiv™ lithium-Ion batteries provide longer runtime, up to 3 times longer life expectancy than Valve-Regulated-Lead-Acid (VRLA), batteries, recharge more quickly, endure up to 10X more discharge cycles and perform better in higher temperatures.
-
Lowest Total Cost of Ownership (TCO)
The longer life expectancy of lithium-ion batteries reduces maintenance, labor, and replacement costs, making it the lowest TCO UPS solution.
-
Environmentally Responsible
Lithium-ion batteries use less material for equal output and up to 99% of the battery elements are recyclable. The longer lifespan of a lithium-ion battery reduces waste and material consumption.
-
Safety Conscious
Safest lithium-ion (LiFePO4) battery chemistry and integrated Battery Management System (BMS) ensure safe and reliable operation.
-
Battery Management System (BMS)
The BMS monitors the lithium-ion battery health at the cell level. It manages the charging, depth of discharge, temperature, and voltage of the battery. The BMS prevents overcharging, ensures safe operation, and preserves the battery throughout its life.
-
Automatic Voltage Regulation (AVR)
When incoming utility power fluctuates, AVR stabilizes the output power without needing to go to battery, which extends the life of your battery and preserves your UPS battery for an outage.
-
Pure sinewave output
Pure sinewave output while on battery to simulate utility power and is compatible with active power factor corrected power supplies.
-
High power factor
0.9 Power Factor provides more actual power to the load increasing power density.
-
Energy Star Certified
A government certification for energy efficiency. This product meets strict energy-efficiency specifications that reduces energy consumption, saving money and helping protect the environment.
-
Programmable outlet groups
Configurable outlets for load management. Cycle power to hung devices and load shed connected equipment, prioritizing critical devices to extend availability while on battery backup power.
-
User-replaceable, hot-swappable batteries
User-replaceable batteries may be swapped out quickly and safely without disruption and without having to turn off connected equipment.
-
Input circuit breaker
Re-settable breaker protects against equipment damage from a short circuit or overload.
-
Network grade surge protection
Network grade surge protection protects connected equipment from power surge damage.
-
Emergency Power Off (EPO)
Remote UPS shutoff in the event of a fire or other onsite emergency.
-
USB management port
USB port to support monitoring and management requirements of the UPS.
-
Optional management and communication cards
Vertiv™ Liebert® Intellislot™ enables network integration connectivity and allows remote monitoring, start-up or restart of the connected equipment. SNMP, Modbus, BACnet and environmental sensor options are available.
-
Free management software
Vertiv™ Power Assist software for local management via USB. Easy to install and allows for simple configuring, monitoring, alarm notifications and management of the UPS. Automatic shutdown options protect connected equipment during an extended power loss and guard against data loss.
Vertiv™ Power Insight software for on-premise and remote UPS monitoring and management with notifications and control of network connected devices. Configurable, automatic shutdown for physical and virtual servers. Includes integrations with VMWare vCenter, Dell VXRail Manager, and Nutanix Prism Central. Provides a single dashboard view of the UPS status, alarms, notifications, and summary data. -
Equipment Protection Plan (EPP)
$400,000 Equipment Protection Plan provides reimbursement or replacement of any connected equipment that is damaged by a power surge while connected to your Vertiv™ UPS.
-

Specifications
The Vertiv™ Liebert® PSI5 Lithium-Ion UPS is a reliable power protection solution for critical IT setups, especially in remote or edge locations. Its lithium-ion batteries last 8–10 years—up to three times longer than traditional VRLA batteries—reducing the need for replacements and cutting costs on both batteries and labor. This results in up to 50% lower total cost of ownership when compared to traditional VLRA batteries. It features automatic voltage regulation (AVR) technology to help guard against power fluctuations and extend battery life, while delivering pure sine wave output in battery mode to protect sensitive equipment. With up to 20 minutes of runtime at half load and 9 minutes at full load, it offers more backup time than many competitors. The 2U-3U Rack/Tower models offer a rotating or gravity sensing LCD display for installation flexibility, providing instant system visibility, remote monitoring support, and delivers up to 98% or greater energy efficiency. Backed by a 5-year full warranty, it’s a low-maintenance, set-it-and-forget-it solution from Vertiv.
