Liebert® PSI-XR 
High Performance Rack-Mount UPS For Network Power Protection
Liebert PSI-XR is a compact, line-interactive UPS system designed especially for IT applications such as network closets and small data centers. It provides reliable power protection for servers, critical nodes, network workstations, large network peripherals, network routers, bridges, hubs and other electronic equipment. Matching battery cabinets are available to extend the on-battery operating time.
Liebert PSI-XR allows you to get more from your UPS and your protected equipment, with features normally found only on more expensive systems:
Greater than five minutes of internal battery backup time at full load provides ample time for an orderly shutdown of connected equipment.
Optional matching external battery cabinets offer more backup time — add up to 6 additional cabinets to extend battery runtime to
meet equipment needs.
Liebert PSI-XR operates at a higher output power factor — meaning less power consumption. This results in your network running at lower power levels and lower heat levels, and ultimately provides a longer network service life.
Remote communications and shutdown options provide remote monitoring and power management — serial and contact closure, USB, SNMP
Ideally suited for:
PCs
Network workstations
Servers
Network closets
Large network peripherals
VoIP
Reliable UPS Protection And Extended Battery Time 
To Keep Your Network Up And Running 
The flexible design of Liebert PSI-XR allows the unit to be configured as a self-standing tower or to be rack-mounted within a 2U space. It is available in four capacities, and both 120V or 230V models.
The UPS features an innovative line-interactive design incorporating buck/boost automatic voltage regulation technology. This protects against utility voltage fluctuation by raising and lowering utility power to the level needed by the connected equipment. It also allows the UPS to prolong battery life by maximizing its time on utility power before going to battery.
Liebert PSI-XR Standard Features:
Flexibility:
Six to seven battery-backed outlets
Allows the Liebert PSI-XR to be more flexible in accommodating additional equipment to be connected to the UPS via the 15, 20 or 30 Amp receptacles.
Configurable input voltage window
Allows the UPS to be properly matched to the incoming utility power and adjusts its input window and transfer points to supply precisely regulated power to connected loads within the selected range. Also enables the UPS to meet the required input voltage when transferring to battery.
Rotatable Display Panel
90 degrees rotatable LED display panel rotates 90° to make the readout of the LED display easy to see in rack or tower position.
Automatic Frequency Sensing
The UPS automatically adjusts to the input frequency, 50Hz or 60Hz.
Rack Rail Kit
These telescoping rails mount to the sides of the UPS to facilitate installation into a rackmount enclosure.
