Internet Office UPS Systems

Internet-ready power protection for computers and printers

Internet Office UPS Systems provides complete power protection for your entire computer set-up, even power hungry peripherals. Built-in modem/fax surge protection and reliable battery backup provide optimum power protection for the Internet user's PC. Available in under-monitor, stand-alone and low-profile configurations.

  • Battery backup prevents your Internet connection from crashing during short power losses and gives you ample time to safely log off during longer ones
  • 6 outlets (3 UPS and surge protected, 3 surge-only protected) safeguard your computer and all peripherals
  • Widely spaced outlet design accommodates bulky transformers without blocking remaining outlets
  • RFI/EMI line noise filtering prevents interference (i.e. from motors, lights and radio transmissions) from affecting your computer
  • Built-in RJ11 jacks provide complete modem/fax surge protection; Internet Office 280 features built-in RJ11/45 jacks to safeguard a modem/network line
  • NEW! 500 VA + 700 VA feature:
    • 2-line modem/fax protection to stop surges on two phone lines simultaneously
    • Built-in serial ports with FREE PowerAlert software for automatic unattended shutdown
    • Convenient battery replacement doors
