I need powered any electronics which has the ground at the potential of the L 230V.
I need +3,3V 17mA - 35mA.
I was looking at DER-507 175 mW Power Supply Using LNK3202D and my idea is
remove R2, flip L with N, on input add MOV 275V , and of course, recalculate output on 4V.
Is it a good idea or would you not recommend it?
