Just to muddy it up even further, we recently put a medical device


>through CE approval and were advised by the examiner that our label
>should read "110/240", and that's the label we passed with.

CE? I am surprised that they did not want it to read "95 - 265 VAC"


That is what most CE equipment works at.


It makes a product that barely works in Japan's 90V realm, and then only on some products.


I had to do a redesign to insure that a production printer (supply)would be marketable/functional in Japanese geographical/voltage markets.

Note: That was a slash, not a dash. This was not a "universal input", it was a dual-voltage device, with a 2:1 switchable primary. I was surprised that they didn't want 110/220 or 120/240 or 115/230. Nope, they insisted on 110/240. Go figure.

Technically it should be 120/240, I think the examiner wasn?t awfully intelligent. Was this a UL CB ?

You'd think so, wouldn't you.

This was an outfit from Canada that specialized in CE approvals.

its probably classified as Professional Medical Electrical Equipment. If its > 16A or >1KW ( 61000-3-2) then it is exempt from the Harmonic tests. So there is no need to put a PFC in there. But it looks like they are gradually tightening this part of 60601. I think if there is a standby mode then that is tested to meet Harmonics, which is easy with a little PFC switcher.
