Scanner inverter outputs Answered

I've just been wondering about the output of scanner inverters for a few projects, what kind of voltages and amperages are they outputting. I have a few little ideas but don't really know that much about their outputs, I gave googling and parts numbers a go but mostly found unrelated pages or had no luck with part numbers...

They output some where between 350 VAC to 800 VAC at around 5 to 6 mA some might be a little but higher but only by a mA or two and they are usally in the 30 to 50 kHz AC range... Some also have a much higher starting pulse in the area of 1200 to 1800 Volts .... What is the length of the tube it was powering ??

Eh the tube was broken, it was an inch wider than A4 paper... Almost ten inches...

About 500 to 600 V.A.C. at 5 mA.

Cool, thinking of things I can do with that now...

not much. its high frequency, low voltage. you cannot use a cwvm to raise the power. its not as good as a transistor setup for a flyback transformer and its not enough power for a plasma globe.

Hrmm It has one possible use but there's no way in hell I'm doing it yet, ya see electrolysis is better at low current, higher voltage, this thing runs off 12V already, got me a transformer for something now... But that is not an initial thing, that is strictly for later plans after initial experiments, which involve some lunacy as you know, also I hate to tell you this but all three bits are sitting on my desk ready to go, tomorrow we'll see just what will happen...

I don't think I'll do the high voltage thing unless I somehow manage to counter the general problems that have stopped these things taking off, not likely...

what were the HV problems?

Nah not HV problems, more the whole system in general, they work to a certain degree but have problems...

FWIW, I tried making a miniature jacobs ladder out of a CCFL inverter, and didn't have much luck; aside from not working, the transformer windings ended up arcing over and shorting out...

It depends on what kind of scanner you have.... Find your scanner number and call the company or google it... Or just post it here and I will look for it....Robots199

I was more or less hoping for a general guess here, surely they're all arounda similar mark. the problem being the scanner was old, like old enough to not be seen on Ebay... I guess I could test it....
