Typical Application
Supply voltage circuit connected previous diagram. Please decide constants filter order keep least when normal supply current flows. this case, please connect (more than (less than load resistance connected between input this case protective resistance (R3=100) must insulted. Sensitivity current regulated output amplifier shows pin. External capacitor between used noise removal. When large current grounded primary side line) ZCT, wave form secondary side distorted some signals doesn't appear output amplifier. please connect varistor diode (2pcs.) parallel. Latch circuit used inspect output level amplifier supply gate current external SCR. When input becomes more than 1.1V (Typ.) latch circuit operates supply gate current gate connected output pin. used open state, please connect capacitor (about 0.047 between Capacitor between used remove noise about 0.047
