Technologia Powtran
Rodzina falowników PI7550
Krótkie wprowadzenie:
Nowa rodzina falowników PI7550 zapewnia bardziej wszechstronne sterowanie silnikami. Wykorzystuje ona zaawansowaną technologię sterowania PWM oraz sterowanie wektorowe, wysokiej klasy moduł zasilania oraz sterowania DSP. Służy to łączeniu z wewnętrzną pętlą prądową do realizacji wysokiej precyzji sterowania w pętli zamkniętej i osiągnięcia stabilności i precyzji prądu i częstotliwości. Kompletnie nowa technika produkcji i sprzęt kontrolny zapewnia lepszą stabilność i niezawodność produktów.
