R Core Transformers

jimmyd53 · 27th February 2008, 06:16 PM

Does anyone know of a retail source for R Core Transformers in the United States? Thanks. James

Have you tried CUI Inc. ?
When I contacted the Australian R-Core agent some years ago they were willing to wind 2 transformers for me, price was about half again the cost of a similar toroid.

Regards
James

Thanks for the tip. CUI Inc is just up the road from me, but I assumed they would not be interested in small orders. I will give them a call. James

Do you mind reporting back what they say? They're not that far from here either.

I talked to John Galaway, Western Regional Sales Manager for CUI Inc., this afternoon. Nice guy. He told me that CUI Inc. has all their transformers manufactured offshore in China and that his company is exiting the R Core transformer business due to soft demand. He further said that even if they were not exiting the line, buying a couple of transformers from him would not be cost effective due to the high freight charge on small orders from China to Oregon. Looks like CUI Inc. is not an option for us, so if anyone has any other ideas please let us know. Thanks. James

so, are you still only considering domestic US sources?

I will give Electro Assemblies a call tomorrow. I have the feeling after talking to CUI Inc and looking at a number of other websites that most of the R Core transformers are manufactured by a very small number of contract suppliers in Asia. Not only do many of the transformers have a very similar look, but the data sheets all seem strangely familiar. I would be interested in buying direct from an Asian distributor if the total cost including shipping was reasonable. James
