The SII series includes a power range from 100 to 800kVA with three phase input and output. The SII uses double conversion on-line technology (VFI) with an isolation
transformer on the output of the inverter. The load is powered continuously by the inverter with a filtered, stabilised and regulated sine-wave supply. The input and output EMI filters considerably increase the immunity of the load to mains disturbances and surges.

  • Isolation transformer on the inverter output
  • High short-circuit current
  • Low input current distortion (12 pulse version)
  • Electronic and galvanic isolation between load and battery
  • Efficiency up to 98.5% in smart mode
  • Made in Europe
