3.5kV power supply teardown
Lodoiska:
Hi!
I know this is an old thread, but just in case some of you are still here... Has anyone tried this power supply with non-sheated 2mm plugs? I also got one, but as it has been specified, the connectors for this are really expensive, when you can find them at all. So I was wondering if someone had tested it successfully with normal 2mm plugs, without bypassing the built-in securities?
Thank you!

And then see the German made WIMA at the output stage.
I remember the days, when we opened anything of quality and it was full with red and yellow WIMA capacitors.
These days, you really have to look for them.

These days you get a lot of red low spec caps from Wurth instead ;D

Hello Lodoiska and welcome to the forum.
I have made my own connectors with gold plated MultiContact 2mm banana plugs for the EPS 3501 XL.
It works really well, is safe to use and no security issues at all.

Hi!
Thank you and than you! :)
You have no idea how much your original post has helped me; I was going mad looking for info on this power supply's connectors. Not even in the manual do they specify what is required!! You were the only one to specify it. And I am lucky you still are a member :)
So, if I understand well, a (quality) non-sheath 2mm banana plug will work? Because a 2mm male to 4mm female can be found easily, and the electrophoresis cables available in my lab are with the new 4mm sheath standard. That would be so much more simpler and economic than finding the right "science" adapter...
(yup, I am that weird, I am going to use this for what it was originally meant... ;P )
Thank you so much,
Lodo

I am traveling right now til the weekend.
Then I can upload some pictures if you want.
No, do not use 2 to 4 mm adapter, that is not safe !!!
I used gold plated 2 mm straight banana plugs and made myself some
holders / spacers out of teflon (PTFE)
On one side of the holder the 2mm banana plug comes out
On the other side a good quality high voltage cable comes out
I have no idea how the original cable and plug looks like but the one I built is perfect for my needs
and 100% safe!
