    I am looking for same cheap transformer that can take 110V/60Hz (US Standard) to 10-12V. I found some for ~40 (Euro without shipping cost + shipped from England). Would anyone provide some suggestion for this type of transformer avaible in US market? I am very appreciated

    As long as I can get 10-12V AC then it will be okay.

    Power lekhanhvinh, voltage means nothing if you don't specific the amperage required or total wattage.

    Perhaps you will be better of with a powerful switchmode powersupply. Many of these can be used with both 110 and 220 volt AC. And it will also have the needed approvals. It will probably cost less than a big transformer. Just a friendly tip :)

    Thank for answering. Can you provide an AC to AC powerful switchmode powersupply that can do 110V/60Hz int to have 12V/15A out?

    It is hard to recommend something since I do not know which country you live in. I suggest you do a search on the net for vendors in your area. Find some alternatives then post them here for comments.
    It would also be useful to more about your application
