Manufacturing standards
A number of different standards or manufacturing standards are used for
the testing and certification of power supplies. These standards are divided
into standards for electrical safety and standards for EMC or radiodistrubances.
Over the time older standards are substituted for new standards making it easier
in terms of testing and safety. The standards listed below comprises the most
common standards for electrical safety and EMC relating to power supply products
within our product program.
