7. A few tips
The industry demands increasingly sophisticated products with safety features that can, in some cases, create problems of use. It is therefore important to limit the number of safety features to those that are really essential, as excessive use can be counterproductive.
Before returning a power supply that doesn't seem to be working, you need to carry out a few checks.
