The figure shows the current of the line current restrictor limit circuit. Once the value of the current exceeds the limit value, the controller relay will cut off the power supply immediately. The current limit value is continuously adjustable from l00mA to 10A. The components of the circuit is shown as above. The whole circuit includs the line current sample and voltage comparator, RS flip-flop and control relay. It is composed of an operational amplifier MA741 and a four - two input NAND gate CD4011.
