1.1kva uninterruptible power supply 2.Double conversion design 3.UPS monitoring software 4.Network RJ45/11 protection 1kva uninterruptible power supply  Key features:H series on-line UPS is an advanced true double conversion on-line topology, the H series isolated gate bipolar transistors (IGBT) for true isolation from AC input. Ideal for data centers in network and industrial applications. Features scalable battery packs for those critical business systems that require long run times. With the H series wide in-put voltage range and near zero tolerance on frequency and voltage variance on the put-put the H series is perfect for the most demanding and delicate of applications.a).Sine-wave outputTrue sine-wave output with less than 3% THD b).Double conversion designZero transfer/complete isolation of input AC c).UPS monitoring softwarePowerful true RS232 communication via the enclosed software manages and safely shutdown operating systems. d).Network RJ45/11 protectionCompleted powerful network and phone line surge protection e).AC surge suppressorPowerful multi-stage surge components exceed IEEE requirements. f).SNMP slot optionAllows for remote monitoring and control via www g).Sleep modeWorry free battery management. The unit turns itself off after ten seconds to conserve battery power when no power needs are detected. h).Battery level indicatorsLED's indicate battery levels i).Load sensingThe incorporated LED load indicators allow IT professionals to manage backup time and balance power loads. j).Low battery indicatorsThe low battery level indicator will warn of eminent UPS shutdown two full minutes before unit shuts down. k).Replace battery indicatorsA preventative measure that indicates when batteries must be replaced to prevent server crashes.  Technical specifications:
