SUMMARY

The discussion centers on the difficulty of finding small 110V to 220V isolation transformers, specifically those rated between 5 to 15VA with leaded connections. Participants note that solid-state converters dominate search results on platforms like eBay, Amazon, and Digi-Key, making it challenging to locate traditional iron core transformers. Suggestions include using Google Images for more effective searches, with specific links provided to products from Stancor and DIY Paradise. The conversation highlights a perceived decline in the availability of these transformers compared to 20 years ago.

PREREQUISITES
  • Understanding of isolation transformers and their applications
  • Familiarity with electrical ratings, specifically VA (volt-amperes)
  • Basic knowledge of online search techniques, particularly image searches
  • Awareness of product sourcing from electronic component suppliers
NEXT STEPS
  • Research "Stancor isolation transformers" for product specifications and availability
  • Explore "DIY Paradise isolation transformers" for leaded options
  • Learn about "Google Images search techniques" to enhance product searches
  • Investigate "iron core transformer specifications" to understand performance characteristics
USEFUL FOR

Electronics hobbyists, electrical engineers, and anyone seeking to source small isolation transformers for projects or repairs.

Believe it or not, I have problem finding a small 110V to 220V isolation transformer! No matter how I typed in the search, I get solid state converters. This is true on ebay and Amazon and Digikey! What happened? It used to be so common and cheap to buy a small isolation transformer, it's everywhere. Anyone has suggestion? I just want about 5 to 15VA ones, leaded. I could swear 20 years ago, you go to Tamura or EWC etc, you'll find them just like that!

To be specific, I mean real transformer with iron core and primary and secondary winding! I can't even take for granted here!:biggrin:

I often use a Google Images search, to help me get to the good hits quicker. I used Google Images and a quoted search on "isolation transformer", and this is one of the pics at the top of the first page -- from Stancor:

Is that what you are looking for?
 
Although that one has cords on it instead of leads...

Here's one with leads -- you could just use the isolation transformer part, and not the follow-on transformer part:

Thanks for the quick reply, what is image search? I am not good with computers!

I am really looking for small 10VA stuffs. I did see some with cord, the 100VA+ stuff.
 
To do a Google Images search, go to Google.com and look for the "Images" link near the top of the page.

Ah, sorry, you only want 10VA. I'd still start with the Google Images search to see if you see something small there...
