One group of integrated circuits using electrical circuit 555 when the load limit

555 limit when one group integrated electrical circuit load circuit is shown. It can limit the large load electric power. When the electricity load exceeds a set value, automat

ically breaking power; when the load to be reduced to below the set value, it can automatically restore power. It uses capacitor step-down, using 555 IC A composition monostable delay circuit. Adjust R4, C4, can be changed variable delay time adjustment potentiometer RP, you can change the operation setting value.
