Hi there everyone,

I recently bought two HP Proliant ML350 G3 Power Supplies, model: PS-5501-1C

The power connector on these is nothing like any others I could find online, maybe because I don't know what to search for.

Hence I am unable to trick the power supply into turning on.

does any one have any experience with this supply and know how to make it work?
 
Start here;

It's an index of PS conversions.
I'm not registered, so I can't do a search.
I did see the G4, though.
 
This is the connector you are looking for, to save you going through them all http://www.rcgroups.com/forums/showthread.php?t=358340&page=2

I'm about to do the same. Don't forget that if you are connecting them in series you need to isolate the DC case earth(via the pcb screws) on one or the AC earth(dangerous if a fault develops and you touch the metal case).

edit:series, not parallel
 
Mine is slightly different, so frustrating, must have tried a hundred combinations right now, it's hard with only two hands :lol:

Thanks for finding one with a similar design though, it will help!

I ended up just buying a 3kw 48v 57a power supply that has already been reverse-engineered, but would still LOVE to make these ones work!
 
Where the heck did you get the 3kw one?
 
Ah - found em...

I need three though :) Hope they are isolated... (yeah dont ask)
 
Oh jeez yeah, very different connector. I didn't look close enough! Let me know if you want any voltages from the unmodded supply that I have, maybe that will give you some pointers. Also, if you open it up you will probably find another manufacturer's model number, possible Liteon, which might point you toward a pinout.
 
Cheeseboy, does this pinout look right?

This is the precise one I purchased:

thanks for the pinout Stevesie, but I am only able to find pins A1, A5, A10, A15, A20, A25, A30, A32. Unless, do the pins mean the little holes in the output side? o_O not the golden spades? because that might make sense :oops: some pins are unlabelled, the little ones beside pin 5 are unlabelled as well as all the pins on the bottom of the output - which I have been told to ignore in my attempts to get it to turn on.

The Gnd labels on the pinout you posted match mine and the 5v Aux. I am unable to test whether the others match although it looks promising.

How do I find the B pins?

any other advice would be appreciated

thanks for your help so far!
 
The labels should correspond to the gold "tabs" on the edge connector. Do the A labels exist on one side of the edge connector or both? A1-A5 for example might be one large gold tab, a single tab might only cover one A number. Does that make sense?
 
I think it would be B11 to ground, which should be on the other side of A11. I think. There might be another pin to ground needed, other supplies need an "Enable" pin grounded. I'm just guessing here, so do be careful!
 
If you look at this post http://www.rcgroups.com/forums/showpost.php?p=15453987&postcount=14 you can see which connections are needed to make my ESP113 supply fire up. That might help you figure that one out. If you go to post #90 of that thread you will see the full pinout of my supply.

A5 MIGHT be remote sense return (negative), and the INSTAL pin also looks like it might be important. Good luck, I hope the smoke stays inside the components.
