Switching power supply wiring method:
L: Connect to 220v AC live wire
N: Connect to 220v AC neutral line
FG: grounded
G: Ground for DC output
+5v: port for outputting +5V point
ADJ: The output voltage is adjusted within a certain range. The rated voltage output on the switching power supply is originally fixed when it leaves the factory, that is, the nominal rated output voltage.
Setting this potentiometer allows the user to adjust the output voltage in a smaller range according to the actual usage, and it is generally not necessary to adjust it.
