Zaresy mocy to 0,25 do 2,2 kW (1 AC 220 … 240 V)
oraz 0,75 do 3,0 (3 AC 380 … 460 V). Wiele możliwości trybów pracy, mnogość opcji, duża sprawność, bezpieczeństwo i małe gabaryty to główne zalety serii Nordac vector mc.
Bezczujnikowe sterowanie wektorowe (1SD) umożliwia przemiennikowi symulację modelu matematycznego, współpracującego silnika co pozwala na dokładną kontrolę napięcia i prądu silnika co w efekcie przekłada się na utrzymanie przez niego założonej prędkości przy zmianach obciążenia.
Podstawowe cechy - Sterowanie wektorem pola ISD, zapewnia duży moment rozruchowy - Wysoka precyzja sterowania prędkością silnika z uwzględnieniem kompensacji poślizgu - Wygodny montaż, programowanie i uruchamianie - Dwie, różnej wielkości kompaktowe obudowy - Bez konieczności odstępu przy instalacji obok siebie - Dopuszczalna temperatura otoczenia do 50°C - Wbudowany filtr sieciowy klasy A - Możliwość sterowania za pośrednictwem interfejsu szeregowego RS 485 - Automatyczny pomiar rezystancji silnika - Dwa oddzielne zestawy parametrów przełączane on-line - Sterowanie sygnałem analogowym od 0 do 10 V (opcjonalnie ą10 V, 0/4 do 20mA) - Dwa programowalne wyjścia przekaźnikowe - Programowalne hamowanie prądem stałym (D.C.) - Wbudowany przerywacz hamowania dla działania 4-kwadrantowego - Regulowane wygładzanie charakterystyki pracy - Skalowalne wyjście analogowe, 0 do 10 V - Odłączalny moduł sterowania i parametryzacji - Wyświetlacz tekstowy z funkcją zapisu danych - Dostępna również przemiennika vector mc w wykonaniu z małym prądem upływu
