Abstract

The invention discloses a protection method for preventing POE power supply equipment from being overloaded, which can effectively control the power supply process and power supply power of the POE power supply equipment and can manage and control the output of a power supply port in real time. And a reliable mechanism is provided to ensure that the POE power supply equipment is not overloaded andabnormal due to overlarge output power, and the power transmission requirement of the POE power receiving equipment can be met as much as possible within the range of rated output total power.

Description

technical field [0001] The invention relates to the field of power supply of electronic products, in particular to a protection method for preventing overload of POE power supply equipment. Background technique [0002] All electronic products need to receive power, and most electronic products transmit power through transformers or power modules; devices that support POE functions can receive or supply power through POE, and the specific method is through network cable transmission and input through the RJ45 port of the device. [0003] During the POE power supply process, there will be excessive output power and overload, resulting in power failure or other abnormal situations. The power supply equipment is required to have an overload protection mechanism to prevent power failure or other abnormal phenomena. Contents of the invention [0004] The purpose of the present invention is to provide a protection method for preventing overload of POE power supply equipment in ...
