High Voltage DC Benchtop Power Supply
motyr:
Hi All,
I am looking for recommendation for the high voltage benchtop power supply.
It must have at least 600V DC but 1000V would be better, adjustable but not necessary from 0V and the maximum output current of 0.5A (1A will be better). Dual output (like 2x300 ... 2x500V) also acceptable, as long as I can connect them in series to get 2x600V ... 2x1000V.
Thanks

Hi,
I dont know much about benchtop power supplies, but i guess you need a lot of money to get your mentioned specs.
Just looked because i was curious and found for example the BK Precision PVS10005 which delivers up to 1000V and 5 A, so it has 5KW.
Looks very nice but pricewise its in the medium 4 digit range ;)

If money is important, build your own. If you only want one unit, you can modify an old power supply. I have one that could do the job or at least come close.
If you want a bench top supply to provide a kilowatt you had better have a strong bench.

Your application? Load? Regulation, PARD, current limit, protection requirements?
Are You qualified to operate dangerous equipment that is LETHAL if a mistake occurs?
Check epay for used DEL or Spellman, also Lambda or Bertran HV supplies, expect very heavy rackmout linear.
Cheaper: series/paralled or modify several tube (valve) Heathkit 1970s IM-17 rated 0-400V and 150 mA each.
See QST, ARRL and others for ham radio TX plate supplies.

It doesn't need to be heavy or large if it's modern, a 1kW switching power supply isn't. HSPY has a relatively tiny 1000V/1A one, available on aliexpress and mentioned here :

PS. shit quality but going be hard to find anything in that price range, especially anything which won't give you a hernia.
