Multi-source mutual-feedback direct-current wide-input troubleshooting device

Abstract

The invention discloses a multi-source mutual-feedback direct-current wide-input troubleshooting device which comprises a shell and a cover plate, wherein the front face of the shell is fixedly connected with the back face of the cover plate through screws. The invention relates to the technical field of troubleshooting devices. According to the multi-source mutual-feedback direct-current wide-input troubleshooting device, a groove is formed in the top of the shell; a handle is rotatably connected between two sides of the inner wall of the groove; the right side of the shell is fixedly connected with a wire interface; a display screen is fixedly connected above the front surface of the cover plate; a control switch and a key are fixedly connected to the front surface of the cover plate andlocated right under the display screen respectively; a main controller is fixedly connected in the shell; and the main controller and a fault detection and elimination module are in two-way connection through a wire. The size of the device is greatly reduced by arranging the main controller and the troubleshooting system in the shell; and in addition, the device can be conveniently carried through the handle and is convenient to use.

Description

technical field [0001] The invention relates to the technical field of troubleshooting devices, in particular to a multi-source mutual-feed DC wide input troubleshooting device. Background technique [0002] The DC stabilized power supply is an energy conversion circuit that converts 220V, 50Hz AC power into DC power, which is an important part of the electronic circuit. In most cases, the energy of the DC power supply comes from the AC power of the power grid. Its function is to convert the AC voltage It is converted into a stable DC voltage. The input of the DC power supply is 220V mains voltage. In general, the value of the required DC voltage is very different from the effective value of the grid voltage. The voltage is processed, and the effective value of the voltage on the secondary side of the transformer depends on the needs of the subsequent circuit. In practice, the transformer may not be used, but other methods may be used. [0003] At present, the troubleshooti...
