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 a 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 […]
