RT-300
Dual-Band Peilsystem
Der RT-300 ist ein universell einsetzbares Peilsystem. Mit dem RT-300 ist es möglich, je nach Anwendung, in zwei verschiedenen Frequenzbändern zu arbeiten. Dabei setzt der RT-300 neue Maßstäbe in Bezug auf Peilpräzision und Empfangsempfindlichkeit. Spezielle Auswertealgorithmen sorgen für eine schnelle und stabile Anzeige.

Zubehör
AU Simulator
Der AU Simulator ist ein kompaktes und einfach zu bedienendes Testgerät für RT-202 und RT-300 DCUs. Der AU Simulator wird durch das zu testende Anzeigengerät versorgt und ist damit für die schnelle Fehlersuche an Bord bestens geeignet.
DC/DC Konverter
Der DC/DC Konverter verhindert eine Beschädigung der Peilanlage durch Ausgleichsströme die z.B. beim Anlassen der Schiffsmotoren erzeugt werden.
