I am designing a isolated flyback with 12V SELV output, according to EN 60950.
The transformer has 4kV isloation between primary and secondary side.
But I am not shure how to deal with the secondary rectifier reverse voltage, that is 80V.
80V is to high for SELV (42V AC / 60V DC), but of course there are never 80V at the output.
Is this a problem to have 80V in the secondary side of the circuit?
