Liebert PSI5 UPS 2880VA 2700W TAA AVR Tower/Rack Network Card PSI53000RT120TAA

Liebert PSI5 UPS 2880VA 2700W TAA

The Liebert PSI5 is a line-interactive uninterruptible power supply rated at 2880VA and 2700W. It delivers pure sine wave output with Automatic Voltage Regulation that corrects input from 83 to 159 VAC without using the battery. The unit is TAA compliant and includes a network card for remote management. It suits network closets, small data centres and critical IT equipment requiring orderly shutdown during outages.

Before ordering check your setup

Verify that the connected load does not exceed 2700W and that the input voltage at the site falls within the 83 to 159 VAC regulation window. Ensure the 120 VAC input connection matches your facility wiring and that adequate space exists for the tower or rack-mount orientation. Confirm the network card interface is compatible with your monitoring software and that the transfer time of less than 6 milliseconds meets your equipment hold-up requirements.

What this replaces and when to upgrade

This UPS replaces older backup units that lack pure sine wave output or AVR across a wide input range. The jump is worth it when equipment is sensitive to waveform distortion or when frequent brownouts drain battery reserves on narrower-range models. It also upgrades installations needing TAA compliance for government or regulated projects. The integrated network card adds remote visibility absent on basic units.
