Three-phase switching rectifiers type 3FSMR are modern designed rectifiers that use the latest technological advances of semiconductor devices (IGBT) and magnetic components (low loss ferrite core).

Main features:

  • output voltage high stability
  • very low output voltage ripple
  • high efficiency level
  • very good input cos φ
  • low noise


  • too low and too high input voltage
  • excessive output voltage
  • excessive output current-current limitation
  • overvoltage from the grid–varistors


  • proper functioning
  • correct mains voltage
  • fault
  • temperature
  • digital LCD V-meter and A-meter


  • environment working temperature 0°C to 40°C
  • dimension: 404x242x480 mm - standalone case
  • forced cooling
