Abstract

The invention discloses power sourcing equipment PSE. The PSE comprises a PSE controller, a first power source, a detection module, a control module and a switching module. The detection module is used for sending a first detection signal to the control module if a voltage value of an output voltage of the PSE controller is changed from a set voltage value to zero. The control module is used for sending a switch-off instruction to the switching module if the first detection signal is received. The switching module is used for switching off the first power source and the PSE controller if the switch-off instruction is received. According to the embodiment of the invention, when the detection module detects that the voltage value of the output voltage of the PSE controller is changed from the set voltage value to zero, the PSE controller and the power source are switched off, so the power is prevented from being supplied to the PSE controller. When no PD (Powered Device) is connected with the PSE, namely when the PSE is standby, the PSE controller in the PSE does not consume electric energy, so the energy consumption is reduced, a standard of an industry is satisfied, and the user experience is improved.

Description

technical field [0001] The present invention relates to the technical field of power supplies, in particular to a power supply equipment (Power Sourcing Equipment, PSE). Background technique [0002] The Power Over Ethernet (POE) standard is a standard used to regulate Ethernet transmission cables to transmit data and electric power at the same time. A complete POE system includes PSE and Powered Device (Powered Device, PD), because PSE is used to The power supply device is a power adapter. The industry strictly stipulates the power consumption of the PSE when it is in standby, that is, the power consumption of the PSE when there is no PD connection. In order to reduce the power consumption of the PSE during standby, the PSE is usually not manufactured according to the POE standard when the PSE is manufactured, and a low-voltage detection module with low power consumption is used to replace the PSE controller with high power consumption. However, after the PSE not manufactu...
