VACON® NXP Common DC Bus

  • Einfache Integration – höchste Flexibilität

    Das Angebot der VACON® NXP DC-Bus-Frequenzumrichter umfasst eine Reihe von Active Front End, Wechselrichtern und Bremschopper-Einheiten. Diese sorgen für eine effiziente Nutzung und Weiterleitung der gesamten Energie in einem System.

    DC-Bus-Komponenten lassen sich in vielen verschiedenen Kombinationen einsetzen. In einem generatorischen DC-Bus-System speist die Lösung mittels Active-Front-End Energie zurück ins Netz. Es eignet sich für Prozesse, in denen ein häufiges Bremsen erforderlich und die Bremsleistung relativ hoch ist. In einem nicht generatorischen System erfolgt die Verteilung der Bremsleistung an die anderen Frequenzumrichter im System; Eventuell vorhandener Überstrom lässt sich mithilfe eines optionalen Bremschoppers und durch Bremswiderstände in Form von Wärme ableiten. Dies eignet sich ideal für kleine Produktionslinien, in denen Bremsvorgänge weniger häufig sind.

    Versorgungsspannung und Leistungsbereich

    Wechselrichter
    380-500 V...1,1-1800 kW
    525-690 V...1,5-2000 kW

    Merkmale und Vorteile

    • Geringere Energiekosten, da das generatorische Front-End überschüssige Bremsleistung zurück in das Netz speist 
    • Niedrige Investitionskosten, da weniger Leistungskabel und einer kürzere Installationszeit notwendig sind
    • Kosten- und Platzeinsparungen, da sich durch ein optimiertes Moduldesign der zusätzliche Projektierungsaufwand verringert und weniger Platz im Schaltschrank erforderlich ist
    • Verringerte Systemkomplexität aufgrund von fünf integrierten Erweiterungssteckplätzen für zusätzliche I/O-Platinen, Feldbusplatinen und Platinen für die funktionale Sicherheit
    • Das Active-Front-End verbessert die Einstelltoleranz des Frequenzumrichters für Spannungseinbrüche/-abfälle und minimiert Oberschwingungsverzerrungen.
    • Einfache Installation von kompakten, optionalen Platinen

    Anwendungen

    Kontinuierliche Bahn- und Rollengangsysteme, Wickler und Abwickler, Kräne, Hubvorrichtungen, Signalbrücken und Laufkatzen, Zentrifugen, Winden, Fördereinrichtungen und Bagger.
