Over Under Voltage Protection Circuit Diagram

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.

Over under voltage protection circuit diagram.

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. The entire circuit is powered with rectified dc supply but the regulated power is connected to timers and unregulated power is connected to potentiometers to get the variable voltage. The under voltage and the overvoltage protection circuit is a circuit which protects you from the higher voltages and the lower voltages conditions. 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 and under voltage protection circuit diagram and will be output voltage of 9 5 volts. This voltage sensor circuit can be used to protects any appliance to voltage fluctuation. Over voltage protection using timers circuit operation. Over voltage and under voltage protection circuit for high and low voltage cutoff.

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. Protection circuits like reverse polarity protection short circuit protection and over under voltage protection are used to protect any electronic appliance or circuit from any sudden mis happening generally fuse or mcb is used for overvoltage protection here in this circuit we will build an overvoltage protection circuit without using fuse.
