Vertiv Liebert PSI5 UPS 1920VA / 1920W – TAA, AVR, Tower/Rack with Network Card

The Vertiv Liebert PSI5 UPS is a reliable, cost-effective power protection solution designed to safeguard your essential devices in school, home, and office environments. With a robust 1920 VA capacity and 1920 W output, this UPS helps prevent downtime and data loss by shielding equipment from power outages, brownouts, voltage sags, surges, and noisy power lines. Built to meet Trade Agreement Act (TAA) requirements, it’s an ideal choice for procurement in government, education, and commercial settings. The PSI5 combines practical performance with flexible installation options, offering a tower/rack form factor that adapts to your workspace—whether you’re outfitting a classroom, a small business IT cabinet, or a home office. A key feature is the integrated Network Card, which enables proactive monitoring and seamless asset management from anywhere on your network. This UPS not only protects hardware but also extends the life of your devices by delivering clean, regulated power and automated shutdown capabilities during outages, helping to preserve important data and minimize costly downtime.

• Power capacity for versatile protection: With a 1920 VA rating and 1920 W output, the Liebert PSI5 can support a wide range of devices—from desktops and workstations to network equipment and small servers—ensuring graceful shutdowns and ongoing protection during power disturbances.
• Automatic Voltage Regulation (AVR) for clean power: AVR stabilizes fluctuating input voltages so sensitive electronics receive steady, reliable current. This minimizes equipment wear, reduces data corruption risk during brownouts, and improves uptime without drawing on the battery for minor swings.
• Flexible Tower/Rack deployment: The PSI5 is designed for versatile mounting in both tower and rack configurations. Its compact footprint and adaptable rails make it easy to integrate into classrooms, IT closets, or home office setups without sacrificing space or access for maintenance.
• Network Card for remote monitoring and control: The built-in (or included) network card enables remote visibility and management of the UPS status, events, and shutdown actions. This feature supports centralized monitoring with compatible software, SNMP, and alerting to help IT staff respond quickly to outages.
• TAA-compliant, reliable protection with long-term value: Meeting government procurement standards, the PSI5 delivers dependable energy protection with a focus on durability and total cost of ownership—protecting investment in technology across education, government, and business environments.

how to install Vertiv Liebert PSI5 UPS

Step 1: Choose the right location — Place the UPS on a stable surface with adequate ventilation and away from heat sources or damp areas. Ensure there is access to outlets, the network connection, and the equipment you plan to protect.

Step 2: Decide between tower or rack setup — If you’re using a rack-mount configuration, install the included rails and hardware according to your cabinet’s dimensions. For a tower setup, position the unit so outlets and the display (if present) are easily accessible.

Step 3: Mount and secure — Attach the UPS securely in its designated space. If rack-mounting, ensure rails are fastened to prevent movement during operation or in the event of a floor vibration.

Step 4: Connect protected devices — Begin by connecting critical devices (such as a PC, monitor, network switch, and a small server) to the UPS’s surge-protected outlets. Avoid overloading outlets beyond the unit’s rated capacity to maintain adequate runtime and protection.

Step 5: Configure network monitoring and power protection — Insert the Network Card into the UPS (or connect it via USB, depending on model) and install the compatible management software on a computer. Configure shutdown settings, notification alerts, and preferred self-test intervals to ensure automatic-safe shutdown during longer outages.

Step 6: Run a self-test and verify — Perform a self-test to confirm the battery and inverter are functioning correctly. Monitor the event log for any warnings and adjust load placement if necessary to optimize performance and runtime.

Frequently asked questions

• What does 1920VA / 1920W mean for my setup? A 1920 VA rating represents the apparent power the UPS can supply, while 1920 W is the real power available to connected devices. This capacity supports a typical office workstation, monitor, and essential peripherals for a reasonable runtime during short outages, enabling a safe shutdown and protecting against data loss.
• What equipment is best protected by the PSI5? The Liebert PSI5 is well-suited for desktops, workstations, small servers, networking gear, NAS devices, printers, and other sensitive electronics commonly found in classrooms, offices, and home offices. Its AVR helps maintain quality power for a broad range of devices.
• Does the PSI5 provide remote management? Yes. With the Network Card included, you can monitor UPS health, voltage, load, battery status, and event logs remotely. This enables proactive maintenance, alerting, and automated shutdowns without onsite intervention.
• Is this UPS easy to install in a mixed IT environment? Absolutely. The tower/rack versatility allows it to fit alongside servers, switches, and workstations in compact footprint spaces, while its management features integrate with common monitoring software used in schools and businesses.
• What is TAA compliance and why does it matter? TAA compliance ensures the product meets procurement requirements for federal, state, and educational purchases. It’s a marker of quality and reliability, designed to align with government purchasing policies.
• What about battery maintenance and replacement? The PSI5 is designed for long-term reliability with scheduled battery checks and routine maintenance. When battery replacement is needed, refer to the manufacturer’s service guidance to ensure compatibility and safe handling.
• Can I expand runtime for more critical devices? Runtime can be affected by load. If you need longer backup for essential equipment, consider balancing the connected load to stay within the UPS capacity, or pairing with additional UPS units for critical subsystems to ensure uninterrupted operation during longer outages.
• Will the PSI5 operate during a power surge? Yes. The UPS provides surge protection and regulated output, shielding connected devices from damaging spikes while maintaining clean, stable power for safe operation and data integrity.
