LinklSwitchg TN2 LMK3202D from der507

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?

Hi Carpenter,
R2 was used as an EMI filter in combination with C1. In case you want to remove, you may check it's effect on EMI.
Overall, your modification in the circuit will still work fine.
