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. [/av_textblock] [av_heading heading='
