Czujnik kolejności i zaniku fazy CKF-317

Odniesienie: M-651-SR

Opis produktu

Z regulowanym progiem asymetrii napięciowej zadziałania.
Styk 1 x NO/NC.

Czujnik kolejności i zaniku faz CKF-317 przeznaczony jest do zabezpieczania silników elektrycznych zasilanych z sieci trójfazowej w przypadkach grożących zniszczeniem silnika, takich jak zanik napięcia w co najmniej jednej fazie lub asymetria napięć między fazami. Zabezpiecza także kierunek obrotów silnika w przypadku zmiany faz przed czujnikiem.

Działanie
Zanik napięcia w co najmniej jednej, dowolnej fazie lub asymetria napięciowa między fazami powyżej progu zadziałania spowoduje wyłączenie silnika. Wyłączenie nastąpi z opóźnieniem 4 s, co zapobiega przypadkowemu odłączeniu silnika przy chwilowym spadku napięcia. Ponowne załączenie nastąpi automatycznie przy wzroście napięcia o 5 V powyżej napięcia zadziałania (tj. o wartość histerezy napięciowej). Przy powyższych anomaliach uruchomienie silnika jest niemożliwe. W przypadku zmiany kolejności faz przed czujnikiem powodującej niepożądaną zmianę kierunku wirowania silnika, czujnik nie pozwoli na uruchomienie silnika. Ponowne załączenie jest możliwe po powrocie właściwej kolejności faz.
