Neon Sign Transformer

Post by Scott Moroch » Mon Aug 05, 2013 3:52 am


After realizing that my current high voltage supply from united nuclear is useless for fusor operation I have begun to search for a neon sign transformer. I found one on amazon that weighs about 23 pounds and appears to be a true neon sign transformer. It is 15kv@30mA.
Here is the link: ... ransformer

Would this work for a fusor amd has anyone ever used this transformer or a transformer by the same company? However I am having trouble figuring out how I would hook the input voltage up to this type of transformer. I know these tradiational 15-20 pound neon sign transformer are ideal, however would a small 2 pound neon sign transformer work? Such as this one: ... mer+ventex

Any help at all would be greatly appreciated.

To repeat once again what gets said on this forum at least every week:

-NSTs are suitable for "demo fusors" but not for neutron producing fusors.

-The connections and general use of NSTs are discussed in FAQ posts by Richard. Hundreds of examples of NST use may be found by searching our 15 years of archives.

-Electronic neon power supplies (your second link) are not known to have any use in the fusion hobby. They are not transformers. They will burn out if treated like the real transformers discussed in the FAQs. Real transformers are heavy and have fluted insulators for the secondary outputs.

If the ample resources on the forums don't solve your dilemma about how to wire the input of an NST, you NEED to get a local mentor who knows a few things about electricity. When you are working with stuff that plugs into a wall outlet, you're liable to get hurt if you don't know exactly what you're doing.
