APC Smart-UPS RT 20kVA - UPS (rack-mountable) - AC 230/380 V - 20000 Watt - 20000 VA - 3-phase / 1-phase - RS-232 - output connectors: 1 - 7U - black

Smart-UPS On-Line provides high density, true double-conversion on-line power protection for servers, voice / data networks, medical labs, and light industrial applications. When business-critical systems require runtime in hours, not minutes, Smart-UPS On-Line can be configured with matching battery packs to comply with aggressive runtime demands. The entire Smart-UPS On-Line family provides value to customers with demanding power environments, including very wide input voltage window, extremely tight output voltage regulation, frequency regulation, internal bypass, and input power factor correction.

• Automatic restart of loads after UPS shutdown
  Automatically starts up the connected equipment upon the return of utility power.
• Temperature-compensated battery charging
  It prolongs battery life by regulating the charge voltage according to battery temperature.
• Plug-and-Play external batteries
  It ensures clean, uninterrupted power to the loads when adding extra runtime to the UPS.
• Rack/Tower convertible
  It protects the initial investment in the UPS when migrating from tower to rack-mount environment.
• Flash upgradeable firmware
  Install maintenance releases of firmware remotely using FTP.
• User-replaceable batteries
  It increases availability by allowing a trained user to perform upgrades and replacements of the batteries reducing Mean Time to Repair (MTTR).
• Automatic self-test
  Periodic battery self-test ensures early detection of a battery that needs to be replaced.
• Predicitive failure notification
  It provides early-warning fault analysis ensuring proactive component replacement.
• Disconnected battery notification
  It warns when a battery is not available to provide backup power.
• Audible alarms
  Provides notification of changing utility power and UPS conditions.
• Frequency and voltage regulation
  It gives higher application availability by correcting poor frequency and voltage conditions without using the battery.
• Power conditioning
  Protects connected loads from surges, spikes, lightning, and other power disturbances.
• Input power factor correction
  It minimizes installation costs by enabling the use of smaller generators and cabling.
• Generator compatible
  It ensures clean, uninterrupted power to protected equipment when generator power is used.
• Cold-start capable
  It provides temporary battery power when the utility power is out.
• Safety-agency approved
  Ensures the product has been tested and approved to work safely with the connected service provider equipment and within the specified environment.
