EMC-Filter CNW 307

Filtercombination (single stage)

Description

Der Kombifilter CNW 307 entlastet das Versorgungsnetz durch Kompensierung der Oberwellenblindleistung. Die harmonischen Oberwellen werden auf THD < 60 % reduziert. Dadurch wird der Wirkungsgrad verbessert und die Leitung entlastet. Die Netzdrossel begrenzt außerdem die auftretenden Netzstörungen, wie Stromspitzen und Spannungseinbrüche des Netzes. Zur Einhaltung der Norm EN 610003-2 oder IEEE 519 empfehlen wir den Einsatz der Baureihe CNW 898. Das integrierte Netzfilter dämpft die sehr hohen asymmetrischen und symmetrischen HF-Ströme, welche vom Umrichter verursacht werden.

Advantages

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

Typical applications

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: IEC/EN 60939 / 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.
