Go ahead and put it on the pwb. We do it anf
it works very well. There is a caveat though -
pay a lot of attention to the layout and final
installation.

Hi Doug!
Ignoring the EMC questions (as I can safely do, being
a product safety division engineer at TUV!) the
enclosure of the open frame supply would have to meet
the same safety requirements as any other enclosure
around a hazardous voltage circuit. The creepage and
clearance distances

Hello Doug,
I think the enclosure of EMI filters is necessary.
The enclosure (normally metallic and, if the filter should work well,
connected to ground) prevents, that for example by radiation, disturbing
signals could get into your filtered equipment.
The filter would be bypassed.

Doug,
We have a piece of I.T.E. equipment that we designed that has dual power
supplies with an EMI filter on the AC input of both supplies. We designed
our own filters for this particular unit. They are simply small through-hole
