12kv solid state neon sign transformer

[ExplosiveAnyThing]

ahahahahaha probably 20mA but NOT 700mW at all

[anotherPCfreak]

12000V x 0,7A = 8400W

It says 700mA at the input.

That arc doesn't look like 700mA. It looks closer to 20-30mA. Check your transformer. I think you may have read the ratings incorrectly.

If that is outputting 8.4 kW with only 120W in, you may have just solved the world's energy crisis.

[Bobensen]

Um... If that was 700mA, your wires would be pretty toasty.... Doesnt look like it.

[shadowdude77]

That arc definitely doesn't look like it's carrying 700mA and I see "30mA" on the transformer next to the 12kVrms, which probably indicates it outputs 30mA.

[Knowlagable]

A couple of questions.

How long were those arcs?

what model of transformer is it?

and does that transformer have open circuit protection?

thanks
