DC non pulsed high voltage power supply

Open sesame...

Yeah, I had my heart set on the 35k one, but it says it can be used for pulsed magnetic systems, so I  dont think its what I need. Lotta good stuff on that site though.

Nah, Mr Spates, I'm sure it will fit your purposes. It doesn't mean the supply is pulsed, it's just saying you can use it to charge a capacitor for those type of experiments. It's DC I'm sure of it. Of course, drop them a mail before you part with cash to confirm. Look like a nice piece of kit for a nice price... in fact I'm slowly talking myself into one!

Unlike Amazing1.com, they don't ship outside the US, unfortunately.

Thanks. I think I will write them just to be sure, by the way if you look on ebay under high voltage power supplies, theres this guy who builds and sells those like you are looking at for around 100 bucks I think. He's been around for a while, so you might have a look, but his are pulsed, thats why I didnt buy one from him.

Whoops, you were wrong. Its an adjustable pulsed out-put.

I've seen what you are looking for before on Ebay... they are very expensive.  The really nice ones 1kV - 100kV , variable,  ~ 5mA output  sell for $700-$1000. 


As for the "it must run off batteries" , don't restrict yourself to that.     You can easily build an inverter to convert 12VDC to 115VAC.  I actually built an inverter earlier tonite out of space parts and got 120VAC out from 8 AA batteries.   

The basic circuit is just an astable multivibrator ... 2 capacitors, 4 resistors, and 2 transistors.  You power the multivibrator off batteries, then run the output (12VAC) into a regular old 12V to 115V transformer you get from radioshack.  And there's your 115VAC from a battery for about $10 in parts.
