Beschreibung
Zusammenfassung:	The utility model discloses a multi-protection power adapter which comprises an AC input terminal, a DC output terminal, an input over-temperature protection circuit, an input rectification circuit, an input filter circuit, a transformer TR1, a PSR control circuit, an output rectification circuit and an output over-temperature protection circuit. Wherein the output end of the output rectifying circuit is connected with the direct current output terminal through the output over-temperature protection circuit; and the output over-temperature protection circuit is used for monitoring the temperature of the direct current output terminal and cutting off the conduction between the direct current output terminal and the output rectification circuit when the temperature of the direct current output terminal exceeds a set threshold value. The over-temperature protection circuit has an external over-temperature protection function, and can cut off power supply to the electric terminal equipment to protect the electric
