Problems solved by technology

However, when the user uses a cable to connect the data center equipment and the data receiving equipment for non-straight-through connection, wiring errors may occur, for example, connecting the power port of the data center equipment with the grounding port of the data receiving equipment, which will As a result, the data center equipment is burned out, so it is necessary to perform current limiting and undervoltage protection on the corresponding interface of the data center equipment
[0003] At present, the interface of data center equipment mostly uses (Positive Temperature Coefficient, thermistor), slow melting fuse, fast melting fuse, air switch, etc. for overcurrent and undervoltage protection, but its current limiting range is limited, so it cannot meet the requirements

Embodiment Construction

[0034] like figure 1 The logic diagram of Embodiment 1 of the overcurrent and undervoltage protection circuit of the present invention is shown. The overcurrent and undervoltage protection circuit is connected between the output port of the data center equipment and the input port of the data receiving equipment, and is used for the data center equipment. When the output port and the input port of the data receiving device are connected through a non-straight-through cable, it is possible to prevent the data center equipment from burning out due to wiring errors. The overcurrent and undervoltage protection circuit includes: a first sampling module 10 , a second sampling module 20 , a comparison module 30 , a control module 40 and a driving module 50 . Wherein, the first sampling module 10 is used for sampling the output voltage (VCC) of the output port, and the sampling voltage of the output port is used as a reference voltage; the second sampling module 20 is used for input v...

Abstract

The invention discloses a piece of data center equipment and an over-current and under-voltage protection circuit thereof. The over-current and under-voltage protection circuit comprises a first sampling module used for sampling the output voltage of an output port and taking the output voltage of the output port as a reference voltage, a second sampling module used for sampling the input voltage of an input port, a comparison module used for comparing the sampling voltage of the input port with the reference voltage, a control module used for outputting a control signal when the sampling voltage of the input port is smaller than the reference voltage, and a driving module used for disconnecting the output port and the input port according to the control signal. By the adoption of the technical scheme of the invention, sampling values of the first sampling module and the second sampling module can be changed to make the over-current and under-voltage protection circuit adapt to different current limiting ranges.

Description

technical field [0001] The invention relates to the field of circuit protection, in particular to a data center device and an overcurrent and undervoltage protection circuit thereof. Background technique [0002] In response to the customer's management requirements for data center equipment, the data center equipment is easy to implement and has no engineering wiring requirements, and the data center equipment interface and line sequence definition are optimized. However, when the user uses a cable to connect the data center equipment and the data receiving equipment for non-straight-through connection, wiring errors may occur, for example, connecting the power port of the data center equipment with the grounding port of the data receiving equipment, which will As a result, the data center equipment is burned out, so the corresponding interface of the data center equipment needs to be protected by current limiting and undervoltage protection. [0003] At present, the inter...
