Over Under Voltage Protection Circuit Diagram

This is because of the high potential.

Over under voltage protection circuit diagram. Generally fuse or mcb is used for overvoltage protection however in this project our aim is to make a circuit which can perform better than a fuse or mcb and overcome the. Short circuit protection reverse polarity protection and over under voltage protection are some of the protection circuits that are used to protect any electronic appliance or circuit from any sudden mishappenings. This voltage sensor circuit can be used to protects any appliance to voltage fluctuation. Over and under voltage protection circuit diagram and will be output voltage of 9 5 volts.

Over voltage and under voltage protection circuit for high and low voltage cutoff. Over voltage protection using timers circuit operation. Both the timers are configured to work as comparators i e as long as the input present at the pin2 of timer is less positive than 1 3 vcc then the. For the lower voltage you can see some flickers in the lights and for the higher voltage one the circuit will be fully damaged.

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. We use primary coil transformer is 380 volts to protect them not damaged by too over voltage. When voltage drop down to 180 volts this voltage as above will entered to diode rectifiers d1 d4.
