EMC Filter CNW 307

Filter combination (single stage)

Advantages

  • Compact construction
  • Different connections (Terminals/cables /bars)
  • Easy and fast installation damping of the harmonics
  • Attenuation of current harmonics
  • Limitation of inrush currents
  • Reduction of mains disturbance, current peaks and voltage drops
  • Increased life time for IGBT‘s
  • Low noise

Typical Applications

Interference suppression of frequency converters with IGBT’s and reduction of harmonics PFC (Power Factor Correction) and commutation (current conduction between thyristors) with fast switching semiconductors.

Technical Specifications

  • Conforming to: VDE 0565-3-1 / EN 133200
  • Test voltage: L-L 2100 V, DC 1s, L-PE 2700 V, DC 1s
  • Overload: 1,5 x I 1 min/h
  • Climatic category: DIN IEC 60068-1
  • Nominal Voltage : 500 V
  • Rated current : 3 – 50 A
  • (1) Voltage drop of line choke: The line choke of the CNW 307/3 and CNW 307/6 has a Uk of 4 %. For current ratings of 10 A off the line chokes have a Uk of 2 %.
  • (2) Leakage current of line filters: The technical data shows the maximum leakage current under normal operating conditions. If two phases are interrupted, the leakage current may increase to 6 times the value.
  • For Europe:
    Short circuit voltage Uk: 2% (at 400 V) Voltage drop: 4,6 V/branch
  • For America:
    Frequency: 60 Hz Short circuit voltage Uk: 4,8% (at 200 V) Voltage drop: 5,5 V/branch
