content: Hi!Am looking for a variable high voltage module.Typical ones are programmable and comes in the ranges 0-5, 15, 30 etc kV at 300uA.Typical brands are spellman, bertan, applied kilovolts and similar.They're typically found in ion optics; mass spectrometers, accelerators, electron microscopes etc.NOT interested in high power stuff like neon sign PSU's, X-ray transformers or similar. I'm far too wimpyAnyone has something like that kicking around? Thanks!

content: Not programmable as in digitally, but I'd prefer it to be voltage controllable.Pretty much anything between 10 and 30 kV <1 mA has interest.Looking for a variable instrument to test out some designs for ion guns/lenses

content: Eh, 10kV and up is not that easy. Isolation tester comes to mind. Had one a few weeks ago but long sold.Was planning to push a 2kV photomultiplier PSU but that's an order of magnitude off

content: Christoffer:I Have some 12 kV 100 ua potted HV modules for avionics CRT use.These give output proportional to input, and require a 8 V squarewave at 40 kHz.I have many from 1990s project, with all information. I am sure you can build a drive H bridge.Small size, sealed modules ~ 75 mm long.These are in USA at moment, but could being to EU in Spring if you want.Would be interested to have some kind of swap as I see we have similar interests.Please contact me via PM if interested.Kind regards and happy holidaysJon

content: Ice Tea:Have checked your ebay store many times in the past! Your PMT supply is nice but I have a bunch already.Jonpaul:I've just purchased a Venus Scientific LU15A 15kV 300uA module from a similar application -DC fed however!I would really like to go higher, voltage wise however.

content: Take a look at Ultravolt modulesLike this one:Ultravolt 2A12-P4 Hochspannung / high voltage DC-DC converter adjustable supplyhttps://www.ebay.de/itm/Ultravolt-2A12-P4-Hochspannung-high-voltage-DC-DC-converter-adjustable-supply/233603223246?hash=item3663d64ece:g:fyEAAOSwotJd4C3~But there are plenty of other adjustable high voltage modules on ebay.

content: On our local Belgium 2nd hand site there is currently a programmable 40kV 7.5mA FUG power supply for sale at 125€ which seems a good price. It is stated as pick-up only, but maybe the seller can be convinced to ship it. It already comes with a matching connector, which would otherwise cost probably as much as the power supply itselfhttps://www.2dehands.be/a/hobby-en-vrije-tijd/elektronica-componenten/m1640594435-high-voltage-power-supply.html?c=4dc4183dfac1254e7aa85845826d5acdBut 7.5mA@40kV is
