I have bought one of these power supplies, and i also have a lower - 30kv model. To achieve nice results, you can use that small multi turn potentiometer on pcb to increase the output power. In my case it goes up even to 100kv.
@@MrTurboturbine Mine unfortunately also started sparking today, after working preety fine for few days. I am wondering, how many turns with this pot is a 'safe level" in this case. I made 10 turns, which is max level, obviously it was too much.
@@rafalg.6901 The usual dumb usage of making sparks is damaging these and many other sources. These don't have surge protection, and they are made specifically to be used as dust precipitators.
You're freaking me out touching that wire like that.

@@rafalg.6901 yea I eventually figured that out, then I burnt out the transformers lol.

Might buy or build one to charge my large pulse capacitor, if it's reasonably priced. For arcs, pretty weedley.
That's cool. It looks like we can easily modify the circuit for increased output.
Maybe it is a powersupply for CO2 laser.
4148 is the diode part name - see en.wikipedia.org/wiki/1N4148_signal_diode
Ok now that makes more sense.
