Dear emc-pstc: Thank You all (Juan, Gabriel, Ben, and Patty) for your responses to my IEC65 questions. I will be ordering an updated copy of the document, however, it may take a little time to obtain, so I have another more specific question i would like you to entertain (if you have the time). My copy of IEC 65 gives me the following values for reinforced insulation, a working voltage of 250Vrms (354Vpeak). My product is a signal transformer providing isolation to and from the telecom port.
-0.4mm distance through insulation (section 14.3.1 a) -3kVrms (4240Vpeak) dielectric test (table IV) -6mm of creepage and clearance, or 5mm of special conditions of section 4.3.3 or 9.3.5 are met (Table II). keep in mind that this is the 1976 publication, so I do not know if sections and tables are consistent in topic with the latest versions of IEC 65. Thanks a lot! Mel Pedersen Midcom, Inc. Homologations Engineer Phone: (605) 882-8535 e-mail: mpeder...@midcom.anza.com Fax: (605) 886-6752
