Low-voltage compound switch

LBFK series low-voltage compound switch refers to connecting SCR and magnetic latching relay in a parallel way, adopting internal single chip for controlling, making SCR undertakes zero-passing switching at the moment of switching i.e. switching on when the voltage passes zero and switching off when the current passes zero; the conducting time of SCR is very short (doesn’t generate heat), and then, the magnetic latching relay will be connected for running. Therefore, it has advantage of SCR switch that there is no inrush current in case of passing zero, and the advantage that…
