Działanie
Na wejście przełącznika doprowadzone jest napięcie trójfazowe (3 × 230 V+N). Na wyjście przełącznika kierowane jest napięcie jednofazowe (230 V AC), tzn. napięcie fazowe jednej z faz. Układ elektroniczny przełącznika kontroluje wartości napięć doprowadzonych faz tak, aby napięcie wyjściowe nie było mniejsze niż 195 V. Faza o prawidłowych parametrach kierowana jest na wyjście przełącznika. Świecenie odpowiedniej diody LED zielonej, sygnalizuje załączenie danej fazy na wyjście przełącznika. Faza L1 jest fazą priorytetową, tzn. że jeżeli jej parametry będą prawidłowe, to faza ta będzie zawsze załączana na wyjście. W przypadku spadku napięcia w fazie L1 poniżej 190 V lub jego zaniku (gaśnie zielona dioda L1), układ elektroniczny przełączy na wyjście fazę L2 (o ile jej parametry będą prawidłowe). W przypadku równoczesnego braku prawidłowych napięć w fazach L1 i L2 (gasną zielone diody L3 i L2), na wyjście zostanie załączona faza L3. W przypadku powrotu prawidłowego napięcia zasilania w fazie L1 (powyżej 195 V), układ załączy na wyjście tę fazę.
