Acestea sunt utilizate pentru comutarea automată sau manuală a sarcinii între "LINIA PRINCIPALA" și "LINIA SECUNDARA" (de exemplu, generatoare).
Acestea sunt disponibile în versiuni de la 45 la 160 A AC1 în configurație în patru poli.
CONTROLUL FUNCTIILOR DE LINII:• secvența de faze și pierderea de fază;
• tensiunea minimă și maximă;
• asimetria de tensiune;
• frecvența minimă și maximă.
Convertizoare de frecventa
În automatizările moderne, convertizoarele de frecvență sunt o componentă importantă datorită nevoii de control al vitezei, în funcție de diverși parametri din cadrul procesului industrial. Folosirea de convertizoare de frecvență oferă utilizatorului un număr de avanataje:
Economie de energie. Acest avantaj poate fi cel mai ușor de cuantificat în cazul pompelor și ventilatoarelor, în cazul cărora consumul de energie scade cu cubul vitezei.
Optimizarea proceselor industriale, reducând timpii în care linia de producție este oprită
Mentenanță redusă
Condiții de lucru îmbunătațite.
