Ken, The closest you can get is UL's category for Transformers (Construction Only) and covered under their category XORU2. These are teransformers that have been cosntructed to various standards and meet the constructional requirements only. Testing is done as part of the end-product.
It is a benefit to have coverage under this category since it would alleviate from submitting transformers and parts list for dissection and construction evaluation. Dissecting a transfrormer is the last thing a product safety engineer wishes to touch! Agree? PETER S. MERGUERIAN Technical Director I.T.L.

Currently, I have a switching power supply, using custom transformers. Now I am looking at submitting this product to a agency... Many transformer manufacturers claim they build to UL ...standards, obviously, this is not considered approved, but are there transformer houses that can manufacture transformers that are considered recognized components under a program similar to a sign shop program, where customers can request custom wound transformers that are covered under the UL recognition ? Thanks for any input, Ken ------------------------------------------- This message is from the IEEE EMC Society Product Safety Technical Committee emc-pstc discussion list.
