OVP stands for Overvoltage Protection, that is, overvoltage protection. When the voltage exceeds the preset level, the power supply is turned off or the output is suspended, which protects the rear circuit from damage due to high input voltage. Applied to the power input inlet of electronic products, to prevent the input power supply voltage is abnormally high damage to electronic products.
