Lm358 Low Voltage Cutoff Circuit

But you need to change a photo diode and the photo transistor in place.

Lm358 low voltage cutoff circuit.

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. Over voltage and under voltage protection circuit for high and low voltage cutoff. When the input dc from the sensor is less than zener voltage the output of the op amp is low and vice versa. 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.

Sensing voltage derived through the 10 k pre set is given to the non inverting ve terminal and this sets the high level cut. O p voltage swing is large. Hi swagatam i have made schematic in multisim and simulate it but it cannot simulate as i intend. The power supply voltage and differential i p voltages are similar.

Applications of lm358 ic lm358 ic based dark sensor circuit. When the input dc voltage is equal to the zener voltage the op amps output is approximately zero. 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.

The lm258 lm258aand lm158 lm158acan be derated based on a 150 c maximum junction temperature. This dark sensor ic lm358 circuit is used to test a light dependent resistor a photo diode and a photo transistor. In a printed circuit board operating in a still air ambient. You can use both ln324 or lm358 but i have shown lm358 in the diagram.
