OVER- / UNDER-VOLTAGE PROTECTION OF ELECTRICAL APPLIANCES: This circuit protects refrigerators as well as other appliances from over and under-voltage. Operational amplifier IC LM324 (IC2) is used here as a comparator. IC LM324 consists of four operational amplifiers, of which only two operational amplifiers (N1 and N2) are used in the circuit.
