Frist，conduct a power on test on the lightning strike limit defective products, and the products have no output. Unpack the power supply and turn it on again, check that there is no voltage across the electrolytic capacitor C1, measure the components between C1 and the AC PIN terminal, and find that the fuse F1 is open (as shown in the figure below).

FAQ

What should be paid attention to when placing the power supply?

2023-07-30

Most low-power supplies without internal fans are designed to be placed horizontally. If there is a problem with the system structure, it is necessary to place the power supply vertically, because the heat dissipation issue should consider the output power at a higher ambient temperature.
