Over-Voltage Automatic Switch off Circuit

Over-Voltage Automatic Switch off Circuit

Over-voltage Protection circuit using TL431 Shunt Regulator IC This circuit protects from high voltage. Automatic Equipment disconnect when the power cross the level of a fixed voltage. This is safety device to overvoltage . As per datasheet –  TL431A is the three-terminal programmable integrated circuit . This is a shunt regulator diode. Look like a transistor. This monolithic IC voltage references […]

UnderVoltage and Overvoltage Protection circuit

UnderVoltage and Overvoltage Protection circuit

Over-voltage and Under-voltage protection Circuit for  High and Low Voltage Cutoff. This voltage sensor circuit can be used to protects the any appliance to voltage fluctuation . When input voltage goes high then the relay will activated and also when the input voltage is below then required level then relay activated. Note– Load is connected with NC and COM pin […]
