Power Protection Features

  • Pure Sine Wave compensates for power fluctuations, protects against equipment damage, and prevents data loss during a power disturbance.
  • Automatic Voltage Regulation (AVR) technology safeguards equipment against a range of utility power fluctuations without battery operation.
  • Up to Seven Battery-Backed OutletsAllows the Liebert PSI5 to be more flexible in accommodating additional equipment to be connected to the UPS via the receptacles.
  • Programmable Outlet Group - Power cycle connected equipment and load shed on battery to extend run time.
  • Advance Early Warning of UPS System Status - offers multiple audible and visual alarms to immediately alert you to an input voltage fluctuation (buck/boost), output overload, low battery or replace battery condition.

Power & Surge Supression Features


Battery Features

  • Wider Input Voltage Window prolongs battery life by allowing the UPS to maximize the use of utility power before transfering to battery when input exceeds specified limits (76 to 146 VAC @120V)
  • External Battery Cabinets can be added as needed for additional runtime.
  • Hot Swappable Internal Batteries - Easy to replace batteries to protect your investment by extending the product life.
  • Full Sequenced Battery Testing - PSI5 UPS includes an automatic and manual self-diagnostic test feature. This provides a comprehensive analysis of the condition of the batteries within the UPS and will notify you when the internal batteries need to be replaced.

Intelligent Networked UPS

New Intelligent Rotating LCD Panel
PSI UPS offers a compact 2U rackmount/tower configuration, with the LCD display panel rotating 90 degrees to make the readout easy to see in either configuration, including output overload, or low-battery or replace-battery warnings.

Independently Controllable Outlet Groups
Two independently controlled pairs of outlet groups can be programmed for load shedding and sequential restart if the UPS is in overload or when selected backup time remains.


2 Year Warranty

The industry’s best warranty – No-hassle two-year warranty with advanced UPS replacement in the event of problems. Shipping is free for both original UPS return and the replacement unit. Optional one-year and three-year extensions also available.
