Liebert  PSI-XR  1000-3000  VA  is  a  compact,  line-interactive  UPS  system  designed  especially  for  IT  applications  such  as  network  closets  and  small  data  centers.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.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.Features:Line  Interactive  design  with  sinewave  outputUp  to  7  battery-backed  socketsExtended  battery  optionsUSB  and  network  communicationsAdvance  early  warning  shutdownMinimum  five  minutes  of  battery  backup  timeConfigurable  input  voltage  window  (220,  230,  and  240V)Data-line  surge  protectionHot-swappable  batteriesCold-start  on  batteryRemote  UPS  monitoring  through  SNMP/Web  CardFully  RoHS  compliantBenefits:Designed  and  packaged  for  flexibility  and  high  availability  0.9  output  power  factor  for  active  power  maximization  Up  to  6  minutes  backup  time  at  full  load,  more  than  enough  to  grant  orderly  OS  shutdown  Liebert  PSI-XR  has  hot-swap  batteries  for  increased  availability  Extended  runtime  up  to  more  than  one  hour  at  full  load  to  increase  availability  Versatile  rack-tower  design  which  adapts  to  all  types  of  installations  Rotatable  LED  display  which  adapts  to  both  rack  and  tower  mounting  Mounting  hardware  and  shutdown  software  included  in  UPS  package  for  increased  ease  of  use
