As far as I can tell those are pretty standard HP feet that are abundant on ePay in any colors. I seriously doubt 3D-printed ones would be any cheaper not even mentioning their poor quality, not even

Thank you Dave, Ordered them. :-) Dave VE7HR

Bernie, That is my backup plan. I own 2 3D printers. ;-) Would prefer to source real parts. Dave VE7HR

You can make your own with a 3D printer. ?Check your local Public Library - they may have free access to a 3D printer. 73, Bernie, VE3FWF

I made a constant current load at work, 100 amps 200 volts, of course with a control loop.? When first connected the loop is calling for max current and it made a big current spike.? As this was

You’re probably subscribed on two different emails that end up at the same place.

One that doesnt give spikes :-)) Any supply with feedback linear or switcher is a potential spike producer ! I am not up to date in this area it is possible that slow-start supplies might be best.

Fixed one last week … all loops unlocked … bad pass element in the +10 VDC supply. td

Hi Dave. I got to thinking a bit about the point Alan made below, and it's a very good one. If you consider the turn-on behavior of an unregulated linear supply (i.e. the classic transformer, bridge

OK, I'll bite-- What kind of power supply would you recommend?? I always thought that a regulated supply would be the safest. Were these linear or switcher supplies that produced the spikes? Thanks,

Yes, he is. There have been no duplicate messages here. That's a Yahoo problem specifically. Joel, you are subscribed at both your sbcglobal.net address and your att.net address. If you let me know

Well done David!

Awesome move... thanks to all involved in it! Bravo! Phil, N6OMM

I did a lot of power supply testing for HP, Agilent, and NGC, including the 6012A/B’s, Here is the spec sheet: http://www.testequipmenthq.com/datasheets/Agilent-6012B-Datasheet.pdf. What you want to

Also thank you for the move. I did not realize it until I got a redirect and log in request. I also didn’t realize I had not been getting the summaries except rarely. Nicely done. I now have the

I too have seen a failed power resistor. ?Other failed item maybe be a leaky diode that then shuts down the power supply. ?If the -40v supply is other than 0, -40v suspect a leaky diode, or shorted
