Wanted 1kV 2A DC supply.

Have no idea where Genome is, or even Oppie. Havent seen post from them in a while.

1k @ 2A is sort of odd ball but I found this one...

CHeers

FOrgot to mention , you may not find a 110VAC input at that power level.

Cheers

Thanks, yes single phase 110V is a problem but also a requirement. The supply I have does it, but was custom made and no longer available. I wonder if I could parallel two 1kV 1A supplies or series two 500V 2A supplies, assuming I can find such.

But I'd rather buy a turnkey solution and concentrate on the less dangerous and litigious parts of the system.

When you inquire about an HV DC supply, you need to also specify load type... capacitive, etc. and ripple figure.

That appear to be not driven by a standard line voltage. I didn't look at the specs, but a 4U rack device doing over 2kW is a clue.

The load is mostly a motor controller at the end of a very long, very poor cable, so I guess it's more or less a resistive load, varying slowly. 1kV is needed to overcome cable ohmic losses which can be over half the supplied power. Ripple? Dunno, it's not like there's a big selection so far, so I'll work with what I can sensibly get.

Sounds terrible.

If he is willing to buy such a supply, he should be willing to replace the cable with a nice SPC custom job that exhibits far less losses.

Contact Dominic Galuzzo at Gamma High Voltage in Ormand Beach Florida...

Do you need 110/230, or 110-230? The former implies that a switch to adapt it to the mains voltage is acceptable, the latter not. If a switch is acceptable, you could put a step-up transformer in series of a converter from hvconcepts.com.

Even better if he could dig up his oil wells and set them up on a bench in a nice warm workshop.

Hi

I'm looking for a commercially available 1kV @ 2A DC power supply. Adjustable, isolated output and single phase AC mains input 50/60Hz and

110/230V. Remote or computer control not needed, just a big knob to wind up the voltage. It will probably be incorporated into a rack-mount box and the eventual quantities are small, tens or maybe 100.

A UK supplier would be easiest.

I'm having problems finding something which does all this, particularly the single phase 110V combination, so while I'm looking, if anyone knows of a supplier, I'd be grateful for any hints. Where's Genome when you need him?

Have a word with Telonic.

We buy our Kikusui PSUs from them.

If he found a way to get "a motor" that far down a well (much less a

1.5kW+ unit), he could hoist it back up, put a proper cable on the thing or maybe even a more local power conversion unit, and put it back down there.

Call it modernization.

Or give up and dig a new well right next to it and start over completely. Heheheh.... NONE SHALL PASS!

Why not one of the 220V to 1KV/2A power supplies that you have found, with a low cost 110V to 220V AC/AC 3KW converter if needed ? These converters, if a "commercial quality" is enough, cost less than 100Eur on Amazon...

Robert

600V 2A supplies (1.2kW) are fairly popular (from Xantrex / Sorenson, etc.), what about two of those in series?

2kW is above the limit for normal 120V outlet, so I'm no surprised that there are few available.

The maximum current from a normal 120V outlet is 16A which gives only ~1900W.

kevin

120 AC in industrial service can have a 20 Amp breaker...

Steve

I can't speak to wiring standards outside of North America, but the generally available circuits around here are 15A (roughly 1500W), with a very few that can do 20A (roughly 2kW). You want up to 2kW _out_, so in the US you'd have a hard time finding a socket to plug the thing into.

Generally, in the US or Canada if you need that sort of power you get a

220V socket wired in.

My self, I would simply pop in a single phase 1KV output transformer driven with a variac, rectifier and filter caps. Jamie
