Product Description: DC-Converter 172-24-SD

Neue Produktankündigung. Der galvanisch nicht getrennte DC/DC Abwärtswandler von 48V auf 24V respektive 28V mit 1000W Leistung für automotive Anwendungen. Die Anschlüsse sind aktuell über Anschlusskabel mit entsprechenden Querschnitten von 6mm2 und 10mm2 realisiert. Bei Bedarf kann auf eine Lösung mit Gewindebolden zurürckgegriffen werden. Das Ergebnis aus der Verknüpfung von modernsten Komponenten und jahrelangem Knowhow! Der DC-DC-Wandler für höchste Ansprüche. Die hardwareseitigen Konfigurationsmöglichkeiten sind mit Shutdown (Shutdown mit -VBat) und ON/ OFF Option (Enable mit +VBat) beispielhaft. Eine Steckerlösung bis 45A ist ebenfalls möglich.
