Hello Joe,
Put a bid price on it that reflects the associated risk.
Or delay the purchase till you can test it with a load.
I suspect that if it powers up, it would probably work in your application.
I have a few bench type HP power supplies and they are all nice and RF
quiet,
but are rated well below the 40A you are considering.
A good test would be to load it down to its rated current and voltage
and monitor noise with a clamp on current probe ( on one lead)
to a low frequency spectrum analyzer
No info in the '82, '89, or '93 HP Test and Measurement catalog
It may not be a HP manufactured product, but rather another manufacturer
made it for HP,
and HP slapped their label on it.
Open it up and look for tell tale signs of the original equipment
manufacturer, possibly on the PCB.
I have a 51V, 57A switch mode PS with a HP label on it, a computer
server PS, but it was made by Astec
and their website showed the same ASTEC model and detailed application info.

This is not strictly time-nuts related, but I know there are a lot of
folks here who have and use HP surplus equipment. I have an
opportunity to buy an HP 62615M switching power supply. It is rated
15VDC @ 40A. I have it adjusted to 13.8VDC. I have Googled, checked
the Agilent site and BAMA, but can't find any documentation or specs.
I want to use this to power an Amateur HF radio and am particularly
interested in any information about how much RF hash this thing might
generate. I don't have an HF rig yet, so I can't test this by trying
it. Any help is appreciated.
Thanks.
