When selecting a primary side AC-DC converter, several technical criteria must be observed. Firstly, the input voltage must match the mains voltage of the respective application. The output voltage and power should be precisely matched to the requirements of the end device in order to avoid overloading or undersupply.
Efficiency is also important, as high efficiency reduces energy consumption and minimizes heat generation. In safety-critical applications, e.g. in medical technology, protective mechanisms such as overload or overvoltage protection are also crucial.
In industrial applications, the service life and quality of the components also play an important role.
