I'm not embarrassed to admit that I love my 6200B. I took it in to

I have a Kikusui PAR80A that I've become attached to. 0-80Vdc @1A, 0-8Vdc @10A
with 1mA resolution in a small but heavy box. Single output, but I have other
PSs if I need more.
What would one use 5Vdc @ 100A supplies for these days? I found 2 HP units in
the garage last weekend.

Hi Bert:
Thanks for your description of the 6632A. I didn't realize they could sink
current. There are three 100W supplies in this family:
6632A 20V 5A
6633A 50V 2A
6634A 100V 1A
I have the 50V model on the way, much better for 28 volt equipment.
The load capacity is not as high as the Ameri
Hello Everyone.
I also own an HP 6632A DC supply. This is a great beast. Its sink capability is
just great to test other power supplies or discharge NiCads. I have a more
powerful DC electronic load, but I almost never use it. Its only drawback is
its size - rackmount - which makes it a bit lar

I can recommend the HP 6626A as well, it has four outputs (2x25W, 2x50W)
and each output has 2x2 ranges for current and voltage.
You need to make your own cabling for t
