Hi all,
i have already seen some topics about the 6632b lab psu, but those are mostly teardowns or people with problems asking for help.
I am thinking about to get one of those as my first lab psu.
Does somebody own one of these? Are you happy with it?
I couldn't find any information if or how far it overshoots if it is powered on.
I hope my english isn' that bad..
Greetings, Hagrid
I have 6 of these at home and a few at work. Plus I have sold metric ton of these to others when I got a bigger batch.
+ really accurate. You can check/calibrate your basic low-cost DVM with these!
I have checked like over 50 units and all of them were still well within 1. year accuracy specifications despite being ages old.
+serial port/GPIB
+ works as a load too!
+ I like the enable/disable feature, no need to turn off the entire power supply all the time.
+VFD display
+easy to modify for front connectors, 15 minutes mod and you can vacuum all that dust in the same time.
+ easy to repair if necessary, good schematics available from agilent. (just don't break the VFD display)
+Low output impedance
+++These have been available here in Europe for like 150 euros, really best bang for buck at that price!
Why buy just one, buy at least 2 so that you can use another one as a load. Or run in series/parallel if you need more voltage/current.
-Loud
-Heavy
-Front panel kind of flimsy design, easy to break the VFD display in transport or with careless handling.
-insanely expensive if you buy new one (~2000 eur)
-runs hot and uses 100W without load. (not really that much problem, unless you try to use 8 of these to power 3.3v 40A load in a small room)
-current limit is slow to react
-more prone to oscillate with nasty load than some others.
