Mini hi voltage generator dc input or ac input?

[ratstar]

Is this thing dc input or ac input?

Hello,

It states 3 to 6 Volts DC input.
I must say, the isolation looks terrible.

COOL THANKS IT WORKED!! =)

I wonder if its a multistage compounding marx generator? It coming out in pulses, I was going to make one, but I just bought this for $2, and it actually worked amazingly.

So now I can test electrostatic actuators and speakers, and this spark gap transistor idea ive got!! Ill probably never finish it, but I was starting to get really good.

RIP steve Jobs.

I checked the volts on it, its 586 volts, no matter what the input volts is.
they put 50,000 volts on the advertisement tho, absolute bullshit.

Hello,

The output voltage might be different with a higher impedance probe to test the voltage.
To test high voltage with a good high voltage probe:

Thankyou Bertus for the nice information as always.

But I doubt it, because its not sparking very far, I could make a video to show you, but its only a tiny dot spark its making.

But... I guess maybe it actually is in the thousands at least, its hard to say. yes, u might be right THANKYOU!

Hello,

Read the following PDF to estimate the voltage.

here it is, it packs a bit of punch.

The description of the voltage converter has such a bad translation that it makes no sense.
Your video shows the output being shorted which they say is not allowed.
Then you have damaged it.

Hello,

What is the distance?
1 to 2 mm?


Bertus

 

[ratstar]

Doesn't matter if you short a transformer or a capacitor as far as I know, not that I know exactly what's in the thing.
But the power supply screen went blank when i was running it, I dont know what happened there.

circled the approximate distance.

These ones Clive plays with are great. I bought 16 some months back.
Running from 4 D cells, they really do pack a punch.

Hello,

They must have chinese voltages.
2 kV or 400 kV as in the ad is a LARGE difference.

Buy very cheap, get very cheap.

I was actually going to make it myself. (I have an original design for one.) But ended up being easier buying, I bought it for $5 the shipping was more than the product was, I wasnt even expecting to hit the door, but it did and it worked! so ill put the project on the shelf and get on with my electrostatic and spark gap stuff.

Thankyou. L
