Electromagnetic Compatibility (EMC)

Electromagnetic compatibility (EMC) describes the ability of an electrical device to function satisfactorily in its electromagnetic environment without affecting its environment unacceptably.
Power Supplies should comply with at least two EMC generic standards:

1. The standard for emitted interference (interference emitted or radiated by the power supply in a conducted manner) and

2. the standard for immunity to interference (protection against external interference).

These generic standards comprise a large number of other substandards, each of which specifies limit values for subranges (e.g. certain types of interference).
