After looking for some power supplies, found DER 736. Matches with my project needs, except that DER consider 85VAC - 440VAC as input. My project needs 85VAC - 265VAC as input.

I need some help to verify if, is only Cin (15uF) and C14 (275V) that will change ?, please let me know if I need consider anything else ?

circuit attached

best regards !

Hi Peter,

If only the input range will change and everything else stays the same (output specs), then yes you can use a single 400V rated bulk capacitor in place of the two in series (C1 C2). C14 should not be removed since this is part of the EMI filter.
