Anleitung für Talema Ringkerntransformator Serie

Talema entwickelt und fertigt ein umfangreiches Sortiment von 50/60 Hz RingkerntransformatorenIn diesem Artikel besprechen wir jede der Hauptserien des Talema-Katalogs, damit Sie die beste Auswahl für Ihre Anwendung treffen können. Jede Serie ist mit spezifischen Eigenschaften für ein breites Anwendungsspektrum ausgelegt.

Ringkerntransformatoren bieten viele wünschenswerte Eigenschaften, wie geringes Rauschen, geringes Streufeld, kleinere Abmessungen, reduziertes Gewicht und höhere Effizienz, die bei vielen Produkten erforderlich oder wünschenswert sein können. Einzigartige Design- und Befestigungsmöglichkeiten bestimmen diese Eigenschaften in jeder Serie.

In unserem Standardsortiment verwenden wir Kerne aus kornorientiertem Siliziumstahl (GOSS). Alle GOSS-Kerne werden im eigenen Haus hergestellt und geglüht.

Alle Teile werden aus UL/CSA-gelisteten Materialien hergestellt und sind vollständig RoHS- und REACH-konform.
