FYI: in that rack, the +15V pulls ~0.5 A more than -15V usually. I think this is due to some RF amplifiers which are powered by this (e.g. the AOM that Manasa set up). The Sorensen's can source ~30A in principle, so we should make sure to set the current limit appropriately so as to not overheat them when there is a short.

Was this power supply not fused for all of its connections? I remember that this was connected to at least one un-fused connection in the past year.

 +15V supply powers the following (from what I see):

1. PMC and MC boards on the rack.

2. RF amplifiers on the rack for the beat signals from the green beat PDs.

3. Beatbox itself.

The beatbox was the one that had an un-fused connection last year. I re-did it properly to go through a fuse quite sometime ago.

I dont see any other un-fused connections now from the +15V supply right now.
 

P.S. AOM driver takes a 0 to +28V power supply and not connected to the +15V
