[QUOTE="ArtiB, post: 283349, member: 13364"] Not my area so comments might be worthless - use it / don't use it rules apply. I always thought switched mode power supplies are noisy when they "work hard". So either a larger one with current headroom will help, or reduce the voltage step. ie if the DC out required is 12 v the 220 to 12 V step is quite a big one. A small transformer to step the 220 to say 24 V AC before the switched mode thingy takes the load off (as it were). Kind of a hybrid between a linear and switched mode but could be easily done.
