• Adjustable voltage sensitivity
  Provides the ability to adapt the UPS for optimal performance in specific power environments or generator applications.
• Adjustable voltage-transfer points
  Maximizes useful battery life by widening the input voltage window or tightening the output voltage regulation.
• Audible alarms
  Provides notification of changing utility power and UPS power conditions
• Automatic self-test
  Periodic battery self-test ensures early detection of a battery that needs to be replaced.
• Battery failure notification
  Provides early-warning fault analysis on batteries enabling timely preventive maintenance
• Battery replacement without tools
  Enables fast battery replacement, lowering Mean Time to Repair (MTTR).
• Battery-protected and surge-only outlets
  Reserves power capacity and run time for connected equipment that require UPS battery back-up while providing surge only protection for less critical equipment
• Boost and Trim Automatic Voltage Regulation (AVR)
  Eliminates voltage fluctuations as a source of AV signal degradation and component power-supply stress.
• Cold-start capable
  Provides temporary battery power when the utility power is out.
• Dataline surge protection
  Provides protection of connected equipment from power surges on the data lines.
• Disconnected battery notification
  Warns when a battery is not available to provide backup power.
• Green mode
  Patent-pending operating mode that bypasses unused electrical components in good power conditions to achieve very high operating efficiency without sacrificing any protection.
• Hot-swappable batteries
  Ensures clean, uninterrupted power to protected equipment while batteries are being replaced
• Intelligent battery management
  Maximizes battery performance, life, and reliability through intelligent, precision charging.
• LCD graphics display
  Text and mimic diagrams that display modes of operation, system parameters and alarms.
• Power-saving outlets
  Automatically cuts power to idle equipment to conserve electricity.
• Resettable circuit breaker
  Easy recovery from overloads; no need to replace a fuse. (Not available on Wall Tap SKUs)
• 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.
• Serial connectivity
  Use any Home Automation network to monitor and control the S20 through its RS-232 serial port. For information on how to communicate with the S20, see APC’s Application Note #102. Crestron and AMX installers should visit their respective websites for information on how to integrate the S20 into those networks.
• Transformer-block spaced outlets
  Protect equipment with input transformer blocks without blocking access to other receptacles.
• USB connectivity
  Provides management of the UPS via a USB port (not available on all models).
• User-replaceable batteries
  Increases availability by allowing a trained user to perform upgrades and replacements of the batteries reducing Mean Time to Repair (MTTR)
