I read in !emc-pstc that Ted Rook <t...@crestaudio.com> wrote (in <se3e96c7....@peavey.com>) about 'red tape and European voltage harmonization' on Mon, 3 Feb 2003:

AIUI, the 253 V upper limit WILL be held. Certainly here at Rayleigh the voltage sometimes gets close to 253 V, but not over. > Do UK >labs will test with 230V + 10% +10%? or just 230 +10% I wonder? Test will certainly be done at 230 - 10%, at which voltage fuses may remain intact while magic smoke is emitted by parts that the fuse is meant to protect. > [snip] > >And of course there is the 50Hz issue which is not trivial for linear power >supplies. What 50 Hz issue? Just that it's not 60 Hz, or something more subtle? -- Regards, John Woodgate, OOO - Own Opinions Only. http://www.jmwa.demon.co.uk Interested in professional sound reinforcement and distribution?
