串联/并联/独立模式功能
The series-parallel function can combine two power supplies into one power supply, expanding the output power range of a single power supply, which brings convenience in some applications. Each of the three independent power supplies can be individually controlled to switch the output on and off at the same time, which is very convenient to use.
