Greetings. I've just been asked what EMC requirements apply to an uninterruptible power supply (UPS). I know that European standard EN50091-2 has been published in the O.J. and therefore probably applies. However, I have no idea what is in this standard. Since it will take me a week or so to get a copy, can someone briefly fill me in on what's in this standard? What tests are required? Thanks for your help. ______________________________________________________________________ Jim Hulbert Tel: 203-924-3621 Senior Engineer - EMC Fax: 203-924-3352 Pitney Bowes email: hulbe...@pb.com P.O.
