The saga of the E3610A bench power supply continues.
Long story short. HP/Agilent broke with tradition and decided to
market a reduced cost power supply. Apparently part of the cost
reduction was eliminating the tapped primary power transformer
and selector switch for selecting the line voltage in use. Ergo,
the E3610A power supply was born. Three variants, one for
100 VAC a second for 115 VAC and a 3rd for 230VAC were
produced. Each voltage rating was assigned an option number.
The units are tagged on the rear with their respective AC
power requirement. A label with check boxes for each of
the available voltages will have a box checked adjacent to
the required voltage.
As previously pointed out by another writer, there are three
different part numbers for ac power transformers used in the
supply. On a lark I gave Keysight's web based part quote
page a whirl. A very polite response was returned and advised
the supply was last supported in 2014 and declared obsolete
in 2019. The message from Keysight stated the part was no
longer available. Thus my plan to buy a 115 VAC primary
transformer to replace the 230 Volt variant fell flat on its
face.
So, it appears I have a few options:
(1) Try to catch a parts unit on e-Bay
(2) Use a voltage converter wall wart or control transformer to
provide the needed 230 from 115.
(3) Add a drop from the 30 Amp 230 Volt service in the room
for the single power supply.
(4) Cannibalize it.
Que Sera
Thanks for all the help from those that provided input.
