Manufacturer: Hewlett Packard HP

Model: 6032A

The photos show the exact item(s) the buyer will receive.

Notes: This supply is in PARTIAL working condition.  The previous owner said the HP-IB interface doesn't work when the unit is hot.  We are not able to test HP-IB interfaces.  When we first tested this, we started at 10V and increased the current draw to about 16 amps, and it shut off the output.  We switched off our load.  Overrange, Disabled and OT lights started flashing and the Volts and Amps became erratic, showing from 0 to 5V and 0 to 0.5A.  Then it calmed down and showed a steady 10V until we applied a load again, and it FrEAkeD OuT again.  The supply was picked up and shaken, and a rattly noise was heard - we opened it, and eventually, a nut (that didn't look like it belonged in there) fell out.  We blew out a moderate amount of dust, reseated the FET and Diode heatsink cards, put it all back together and ... it works.  We were able to sink 20A at 60V, 40A at 30V, and 50A at 10V, with no difficulties, for a couple of minutes' testing.  Maybe some dust was making an intermittent fault, maybe the nut was doing something nutty, maybe something else was bad in there, but we are offering this supply for sale AS-IS.  The display is bright and clear, and the controls responded normally to user input.  The fan runs.  No other testing was done.
No manuals, cords/cables, or additional items are included if not listed or shown.
