  • True online double-conversion topology and zero transfer time to battery ensure high reliability.
  • Watch-dog design of DSP (Digital Signal Processor) increases reliability.
  • Cold-start capability provides temporary battery power when the utility power is out.
  • Fan failure detection alerts users to failed fans.
  • Hot swappable batteries ensure continuous operation even when batteries are being replaced.
  • Optional external battery pack for easy scaling of longer backup time.
  • Operation temperature tolerance up to 50°C ensures critical loads’ continuity
  • High output power factor 0.9 provides more real power to critical loads.

Green & Low TCO

  • High input power factor (pf > 0.99) and low harmonic distortion (iTHD < 5%) save upstream investment.
  • Up to 94% AC-AC efficiency and 97% efficiency in ECO mode result in marked energy cost savings.
  • Wide input voltage range reduces the chance of using the battery and extends battery life.
  • Intelligent battery management sustains battery life and performance.
  • Fan speed control by load level maximizes efficiency and reduces audible noise.


  • Load segment control allows less-critical loads to be disconnected during blackouts and saves battery runtime for important loads.
  • Convertible rack and tower configuration in 2U size cabinet.
  • Excellent local communications through rotatable LCD display.
  • Intelligent management software connectivity via RS232 or USB port.
