Lm358 Low Voltage Cutoff Circuit

Hi swagatam i have made schematic in multisim and simulate it but it cannot simulate as i intend.

Lm358 low voltage cutoff circuit.

This voltage sensor circuit can be used to protects any appliance to voltage fluctuation. 3 tested 220v high and low voltage cut off circuits using ic 324 and transistors. When the input dc voltage is equal to the zener voltage the op amps output is approximately zero. The power supply voltage and differential i p voltages are similar.

The lm258 lm258aand lm158 lm158acan be derated based on a 150 c maximum junction temperature. Over voltage and under voltage protection circuit for high and low voltage cutoff. The dissipation is the total of both amplifiers use external resistors where possible to allow the amplifier to saturate or to reduce the power which is dissipated. You can use both ln324 or lm358 but i have shown lm358 in the diagram.

But you need to change a photo diode and the photo transistor in place. Applications of lm358 ic lm358 ic based dark sensor circuit. When the input dc from the sensor is less than zener voltage the output of the op amp is low and vice versa. In high and low voltage protection circuit we have used an lm358 op amp which has two outputs connected to 2 and 3 number pins of pic microcontroller.

And a voltage divider is used to divide voltage and connects its output at 4th number pin of pic microcontroller. When the input voltage goes high then the relay will be activated and also when the input voltage is below then required level then relay activated. May be i connect something wrong. In a printed circuit board operating in a still air ambient.
