Hi,
I need to investigate if a flyback transformer is suitable for an application.
Product requires to pass EN 60255-5 dieletric tests of 2kV /50Hz and impulse tests of ±5kV 5 positives & 5 negatives 1,2/50µs.
So does this mean the transformer selected must have an isolation of atleast 5kVDC , or does a transformer with lower stated isolation (like 2kVrms) will withstand higher impulse test (>2kVrms) since it is a pulse wave form unlike 50Hz continuous sine wave used in dielectric test?
Experts plz convey your opinion..
Thanks,
