This is the simple inrush current limiter circuit diagram. Q1 is an npn Darling-ton and Q2 is a prip Darling-ton. MOV1 is a metal-oxide varistor and R8 is an thermistor for limiting inrush current. This circuit limits ac line current to a load. When a predetermined interval has passed, RY1 shorts out thermistor or resistance RB. R4 can be 150 kQ if R9 is not used. If power is removed, ready for immediate restart.
