For IEC 62368-1’s Annex G.9 on IC current limiters, one of the stated conditions is that the IC is supplied by a source whose output does not exceed 250VA. Can you provide some background on this change?
Annex G.9 is being overhauled in Edition No. 3 of IEC 62368-1, including a new test program replacing the existing three test programs. A 250VA power source will be used for testing, unless the IC CL manufacturer wants to specific something less, which then will be documented as part of the certification as a component consideration.
