ANWENDUNG

Die elektronische Bremsgeräte ermöglichen das verschleissfreie Abbremsen von Drehstrom- und Wechselstrom-Asynchronmotoren.
Die Bremsgeräte werden für Antriebe eingesetzt, die aus Sicherheits- und Funktionsgründen zuverlässig abgebremst werden müssen.
Die Bremsgeräte können auch nachträglich in schon bestehende Anlagen eingebaut werden.
