Main Features


  • Worldwide highest output power level and greatest extra headroom

  • Three or Single* phase very wide range of AC line operation with APFC

  • Easy interfacing to the 3X 400V** distribution without Neutral connection

  • Reduced current draw and line cabling cost, saves lots of copper

  • No more line-to-line balance problems, moreover the amp helps to keep the best symmetry betweenphase conductors in 3 Phase operation mode

  • Fault-tolerant to power line anomalies, still operational with 2 phases

  • Network control over standard ETHERNET




  • Full soft switching implemented with very high power conversion efficiency

  • Supercompact size and small weight in rugged 1RU steel case

  • Easily readable large format display and accurate output level metering
