Default 5000V power supply!

Anyone into crazy high voltage stuff? 250v to 5000V power supply. Id be scared to have it on my bench. What if you slip when adjusting voltage?

Check out this Ebay item
SHANDON VOKAM 5000-250V laboratory electrophoresis psu on eBay (end time 10-Apr-11 17:01:35 BST)

Done PCB@S and mechanicals for PSU's for electron microscope dev, 35kV 10kV and a few 1-1.5kV in same box, got to take care. Special connectors with extra long path for creepage, 10mm polycarb sides, 20mm gap then second layer. Interesting when things go wrong

I have a 1kV supply, and also routinely test automotive ignition coils at 35 to 60kV...

I bought a 3kV electrophoresis supply a few years ago to check and reform HV caps from my Nd/Yag lasers. Super handy and they can be had CHEAP on ebay.

You know 50 t0 500 volts is the most dangerous range. Higher voltages usually jolt you off the connection.(unless they can also source high current like transmission lines). So building big power amps can be more dangerous than working with neon transformers (17kv?).

I remember the first time I got zapped on a speaker cable.
At the time I didn't realize that there was in excess of 120v p-p until I went back and did the math as it was a rather large amplifier(yeooow)! jer

Today at work I ran a test dumping 14 volts and 730 amps into a single heat sink using 3 IGBT's. The voltage is not too high, but still 10,000 watts into a sink is pretty impressive. 3.6 gallons per minute of water to keep the devices under 70c I will be keeping my eyes out for sinks going in the bin. The power supply would be fantastic for a true pass monster, but those don't ever go in the bin.

Hmmm, I was mocked for my habits of "dumpster diving" at my former employer. Of course, due to this habit, and others, I have no space in my basement, and a bloody mess in my apartment. And I am the landlord!

I do however have some rather interesting items around here.
