Re: Power Supply Crowbar

2005-11-23 by djbrow54

Thanks for the replies.  I moved some modules around some more and 
seemed to find a configuration that hasn't current limited yet.  I 
don't want to add another power supply as I'm limited for room.  I 
started designing a voltage sequencer but decided to monitor it for a 
while and see how it does.

Interestingly, though, I measured all four power supplies.  The one 
that current limits has the -15V coming up nearly 25 mS later than the 
+15V.  I put a photo in the DJB's System folder.  The one that current 
limits is the upper right. - Dave
