Smart-UPS Features & Benefits

  • Boost and Trim Automatic Voltage Regulation (AVR)
  • Gives higher application availability by correcting low and high voltage conditions without using the battery (not available on all models).
  • Intelligent battery management
  • Maximizes battery performance, life, and reliability through intelligent, precision charging.
  • Power conditioning
  • Protects connected loads from surges, spikes, lightning, and other power disturbances.
  • Temperature-compensated battery charging
  • Prolongs battery life by regulating the charge voltage according to battery temperature.
  • Automatic restart of loads after UPS shutdown
  • Automatically starts up the connected equipment upon the return of utility power.
  • Automatic self-test
  • Periodic battery self-test ensures early detection of a battery that needs to be replaced.
  • Disconnected battery notification
  • Warns when a battery is not available to provide backup power.
  • Network manageable
  • Provides remote power management of the UPS over the network.
  • Audible alarms
  • Actively let you know if the unit is on battery, if the battery is low or if there is an overload condition.
  • LED status indicators
  • Quickly understand unit and power status with visual indicators.
  • Serial Connectivity
  • Provides management of the UPS via a serial port.
  • USB connectivity
  • Provides management of the UPS via a USB port (not available on all models).
  • Disconnected battery notification
