Abstract

The invention relates to the technical field of power supplies, in particular to a high-performance high-power water purifier power adapter with over-temperature protection indication. The high-performance high-power water purifier power adapter comprises an input port, an output port, a rectifying and filtering module, a switch conversion module, a main control module, a PFC (Power Factor Correction) module, a voltage stabilization output module and an over-temperature protection module, wherein the output end of the rectifying and filtering module is connected with the input end of the PFC (Power Factor Correction) module; the output end of the PFC (Power Factor Correction) module is connected with the input end of the switch conversion module; the output end of the switch conversion module is connected with the input end of the voltage stabilization output module; the output end of the voltage stabilization output module is connected with the output port; the over-temperature protection module comprises a thermistor RT1; and the thermistor RT1 is connected with the main control module. By arranging the over-temperature protection module, when the temperature of the power supply is too high, the resistance value of the thermistor RT1 can be reduced, so that the work of the main control module can be interrupted, and the power supply is protected.

Description

Technical field [0001] The present invention relates to the field of power supply, and more particularly to an overwhelming protection indicating high performance high-power water purifier power adapter. Background technique [0002] With the rapid development of electronic information technology, the electronic equipment and systems of large-scale integrated circuits are widely existed in various areas of modern life, while water purifiers are one of many home appliances. [0003] When the water purifier power supply is operating in high temperatures in high temperatures, the power supply is very prone to failure due to the high temperature, thereby burning damage. Inventive content [0004] It is an object of the present invention to provide an overwhelming protection indicating high performance high-power cleaner power supply adapter in prior art. [0005] The object of the present invention is achieved by the following technical solutions: a high-performance high-power clean...
