Mexico Mains Voltage

I understand that Mexico uses a 220V Wye distribution system such that the single phase voltage is 127V. What low line and high line voltages should one consider as being "normal" where equipment should continue to operate as intended? I ask this because I doubt that 127V is really the nominal vol

Pacemaker susceptibility (immunity) for RF fields

Hello Group, I'd like to know if someone can give me the following information about the susceptibility of pacemakers to electromagnetic (RF) fields: - applying standards - limit values (Electric and/or Magnetic fields) - HTTP texts - PDF material - Books Thanks in advance for your help and Bes

RE: Network Camera and EMC?

John, the ENs that you will use will depend upon the intended application. For emissions, EN 55022 applies for ITE applications, EN55103-1 for professional use and there may be other standards for other applications such as instrumentation and process control. There are at least two immunity stand

John, I forgot to mention that I assumed your camera is for professional, process control, or educational use. Leslie Leslie Bai wrote: John, For US, FCC Part 15B, for Europe, EN61326. Watch out the emissions, if you havn't done anything on the "direct connection to 10/100BaseT". I wou

Re: Network Camera and EMC?

John, For US, FCC Part 15B, for Europe, EN61326. Watch out the emissions, if you havn't done anything on the "direct connection to 10/100BaseT". I would strongly suggest you make a pre-compliance measurement with sufficient confidence level before going to an accredited lab. I recently helped
