RE: 61000-4-8 Ground Plane

61000-4-8 is an immunity test. It totally immerses the EUT in a magnetic field at 50 Hz. I still don't know what the ground plane is for. --- This message is from the IEEE EMC Society Product Safety Technical Committee emc-pstc discussion list. To

RE: TNV-2 to SELV Spacing

Current editions of UL 1950/CSA 22.2 No. 950 (3rd Ed) and EN 60950 (2nd Ed 4th Amd) would require BASIC INSULATION (see 6.2.1.2) between TNV-2 SELV. I believe that a working voltage of 150VDC (Max TNV + some left over on SELV side) and 200Vpk (ringing) is generally accepted as the working

RE: SAE testing

Dear All, Last year I had an ITE product for use in vehicles Listed under UL1950. At 13:11 15/06/2000 -0500, Loop, Robert wrote: Cyril: I don't believe there is a safety (UL) requirement for ITE equipment that will be installed in a vehicle. I have been writing a test plan for a customer

AW: TNV-2 to SELV Spacing

Gary, between TNV2 and PE (ground) the only requirement is functional insulation. For max TNV2 (120Vdc) the following spacings apply: clearance: 0,6mm (table 2K last column) creepage: 0,6 up to 2,4mm depending on the PD and MG (table 2L) eg for PD 2 MG

RE: CE Markings for A.C. Mains

Hello Joe, What is the reference for the markings? Depending on the standard used for a mains plug you may be required to mark the terminals L and/or N on the plug. However, this usually applies to rewireable mains plugs and not molded ones. Regards,
