Description of the Invention: [Technical Field] The present invention relates to a power supply device, and more particularly to a plug-and-detect function for preventing a wave current or voltage surge when installing or removing an external device Power supply unit. [Prior Art] A general distributed power system or a servo power supply device supplies power to a plurality of device modules. However, due to the surge current or voltage surge in the installation/removal process of the device module, it is usually necessary to turn off the power supply device before installing/removing the device module to avoid causing the device. The module or power supply unit is damaged, but this is inconvenient and seriously affects the operation and use of the equipment module. In order to solve the above problems, there is a commercially available power supply device that can be freely installed/removed in the case where the power supply is turned on, that is, a power supply device having a hot-swappable design, which can avoid the device module. Surge current or voltage surges are generated during installation/removal. The power supply device of the hot plug design is mainly a connector having a plurality of conductive terminals of unequal length, a control integrated circuit (IC), and a power control circuit. The plurality of conductive terminals are connected to the joints of the device modules, and the control ic monitors the connection state of the conductive terminals and the joints, and the conductive terminals and the joints of the power supply device during the device mounting/removal process Connection/separation, the control IC can control the power supply to temporarily stop supplying power to avoid surge current or voltage surge. In the above hot-swappable design, having conductive terminals of different lengths
