The CSA publishes design guides for its clients that are somewhat useable by developers.
FWIW, UL60950-1 specifies, in addition to the stated requirements, IEC61558-x for some general xfmr tests, and UL 1585 (to be obsoleted by UL 5085-x) for Class 2/3 power sources. The comment by Mr Woodgate is good advice - as my employer's designers seem to have many problems with using the 'raw' safety standard as a design guide. So for each project, I write some summary tables of construction requirements, performance/test requirements, and spacings that would apply to the particular project. For component transformers, I point all new product designs to use only IEC61558-x and/or UL5085-x, which can get them into most IT and consumer products. luck, Brian From: [email protected] [mailto:[email protected]]On Behalf Of MacArthur, Don Sent: Thursday, May 08, 2008 8:48 AM To: [email protected] Subject: Transformer Safety Design I am looking for a comprehensive standard, book, or technical article which describes designing a transformer to pass the safety requirements (Creepage, Clearance, Insulation Properties, etc.). Overall product must pass UL 60950. There seems to be a lot of standards out there to choose from. I would like to receive suggestions on best possible one(s) to purchase.
