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
