The basic working mode of the power supply
The basic working modes of power supply can be divided into constant voltage output mode (CV), constant current output mode (CC), series mode, and parallel mode. In constant voltage mode, the output current of the power supply varies with the load to ensure a constant output voltage. In constant current mode, the output voltage of the power supply varies with the load to ensure a constant output current. The output connection of parallel or series mode must be independent, and the output of one power supply device can also be connected to the output of another power supply device.

In constant current mode, the output voltage of the power supply varies with the load to ensure a constant output current. The output connection of parallel or series mode must be independent, and the output of one power supply device can also be connected to the output of another power supply device. In order to obtain a larger output voltage, series mode can be adopted, and in order to obtain a larger output current, parallel mode can be adopted.
1) In series mode, due to the addition (or subtraction) of voltages, the maximum current is determined by the power supply device with the smallest set value, so the current of all devices is equal.
2) In order to increase the total output current, parallel mode can be adopted. At this point, the output voltage of all devices is the same, and the magnitude is determined by the power supply device with the lowest rated output voltage. The total current is the sum of the currents of each parallel branch. If the specifications of the power supply devices used are the same, please check if the current distributed on each power supply device is even when parallel. As the current flowing through each power supply device during parallel connection is the same, if other types of power supply devices are used without overload protection, such voltage may be damaged by current.
