Agilent E3633A DC Power Supply

[Al]

Hi All,

Hope someone can offer some advice here. I got a Agilent E3633A DC
Power supply second hand from overseas.


I swapped the line voltage to 230 for my country. The fuse in it
currently is 6.3a 250v (reccomnded for 110v operation) but for NZ a
3.15a 250v fuse is reccomended.


When I power it up I get one beep and the display self tests for a
second before going blank and none of the buttons do anything.


Sounds like a controller issue of some sort?


Yes, I know I need to change the fuse, but with no load attached, I
cant imaging it being able to detect it has the wrong fuse intstalled
and should power on ok?


Anyone have any other ideas?


Cheers

Did you ever figure this out?

On some instrument you need to move the fuse over to select the right line voltage.  We had a similar problem and found the fuse was in a little holder marker 110V and if you turned it over there was a 220V slot.  Moving the fuse over and replacing solved the issue.  Not sure about this one though, I'd consult the manual.
