Abstract

The application provides a power supply fault detection device; the power supply fault detection device is electrically connected to a power supply unit, the power supply unit is used for outputting astate signal in an abnormal state, the power supply fault detection device comprises a control unit, a conversion unit and a test unit, the control unit is used for receiving the state signal and outputting the current to a conversion unit according to the state signal; the conversion unit is used for receiving the current output by the control unit and converting the current into a voltage; andthe test unit is used for testing the voltage. According to the power supply fault detection device provided by the embodiment of the invention, the fault type of the power supply can be identified through the voltage obtained by the test unit, so that the debugging time of the power supply fault is effectively reduced.

Description

technical field [0001] The present application relates to the technical field of power supplies, in particular to a power failure detection device. Background technique [0002] Usually, when the electronic equipment is running, the power module will be shut down due to some unexpected abnormal behavior. At this time, the user does not know what causes the power supply module of the electronic device to be turned off, which causes inconvenience to the user. Contents of the invention [0003] In view of this, it is necessary to provide a power failure detection device that can identify the type of power failure, so as to effectively reduce the debugging time of the power failure and facilitate the use of the user. [0004] A power failure detection device, electrically connected to a power supply unit, the power supply unit is used to output a status signal in an abnormal state, the power failure detection device includes: a control unit, the control unit is used to receiv...
