[0001] The utility model relates to the technical field of DC power supply cabinets, in particular to a combined DC power supply cabinet. Background Art

[0002] A DC power supply cabinet is a new type of DC system with digital control, protection, management, and measurement functions. When commissioning the DC power supply cabinet, first connect the AC power supply and test whether the AC dual-power switching device works properly and whether the voltage at the lower port of the dual-power switching device is normal. After the AC part is tested normally, sequentially close the AC switches of the charging modules and observe whether the modules start normally and measure the output voltage and polarity of the modules.
