High Performance Single-Phase Filters FN2070

Multi-stage Performance AC/DC EMI Filter


Multi-stage Performance AC/DC EMI Filter

  • Rated currents from 1 to 36 A
  • High differential and common-mode attenuation
  • High frequency attenuation
  • Optional medical versions (B type)
  • Optional safety versions (A type)

Features and Benefits

FN2070 two-stage filters are designed for easy and fast chassis mounting
FN2070 B versions without capacitors to earth comply to 1MOP for ME (medical equipment) acc. IEC 60601-1  
FN2070 A version with low capacitance to earth for safety critical applications with necessity for low leakage currents
All filters provide a high conducted attenuation performance, based on chokes with high saturation resistance and excellent thermal behavior
FN2070 two-stage filters are designed for high frequency attenuation
FN2070 filters are also available as single- stage filters (FN2030 series)
FN2070 filters are also available with differential mode choke (FN2080 series)
Various terminal options allow you to select the desired connection style
