Product Details


This series is a double conversion Power Converter which produces stable pure sine wave voltage and frequency output (O/P). With the Converter, you can protect your equipment from most of the power problems, including power sags, power surges, and line noise, etc. With the common neutral topology, the Converter provides internal connection from AC I/P neutral to AC O/P neutral; thus, it does not need to use an isolation transformer to provide 0 volt from AC I/P neutral to O/P neutral. This feature will reduce the interference to loads of communication or video system.


With outstanding performance & reliability, the unique benefits of the Converter include the following:

  • Common Neutral, Double Conversion Topology
    (O/P Neutral to I/P Neutral is 0 volts normally)
  • Input Power Factor correction
  • Low Noise Smart Cooling Fan Design
  • High Efficiency, New Full-bridge Inverter Design
  • Full Function LCD Display
  • Automatic Restart of Loads After Overload Shutdown
  • AC Input Generator Compatible
  • Remote Emergency Power Off
