Re: 8902A Power Supply issue
Exactly what Peter said! Running out of headroom at low line, high load and high regulator¡¯s reference is a bit shameful, so in good designs one makes sure that with everything against them,

Re: 8902A Power Supply issue
Remember that the supply must have sufficient voltage pre-regulator at the lowest line voltage and the highest load the supply was designed for. Also it must be the lowest voltage of the ripple.

Re: 8902A Power Supply issue
I'd think -20 volts and +8 volts might have been a better design. Just being conservative without thinking of what they really did. Could those voltages be a result of light loads on the bulk

Re: 8560E New to Me: Some Issues & Questions
The hours indication in Recall is in hours, not tenths.?? Sounds like a lot of time, but if it works as you describe, I would not be concerned. I have an 8560E with ~15000 hours and it has worked

Re: HP853A/8559A Problem
What kind of conditions has the system been stored in? Any dampness? If so then the rail guides may have some aluminum alloy corrosion making the fit even tighter. The probable solution is to remove

Re: HP853A/8559A Problem
I finally have time to work on my SA. I tried to remove the 8559A from my HP853A by loosening the Locking Knob and extracting it about an inch. I tried removing the module but it doesn't budge. The

Re: What's this mains plug with live/neutral horizontal when earth is at the top?
I have heard the opposite that DC is more dangerous than AC. But I am not keen to grab either. Fortunately this power supply can work as constant current or constant voltage and will switch between

Re: What's this mains plug with live/neutral horizontal when earth is at the top?
Actually probably not. You have to get the current into the wet stuff under the skin. High voltages like that arc over the skin, char it, and travel on the outside. Companies that make capacitor

Re: What's this mains plug with live/neutral horizontal when earth is at the top?
A search for "AC PLUGS" brought up a pdf which indicates that it is probably a "NEMA 6-15P". A search of the internet for "NEMA 6-15P" produced this link

All you need to do is poke around on homedepot.com or similar for plugs/outlets rated greater than say, 200V. Here's a pretty much identical plug
