DPS-1520AB Server Supply Hotswap Breakout

Details

I wanted an easier way to connect power and seen other boards available for server supplies that looked great but none that i found for the DPS-1520AB. series supply
so I set out and made my own based on various pinout information found online

The Supply Side receptacle: (ON THE DPS-1520AB)
Internal Header (Amphenol FCI Part: 51939-104LF)

Breakout Board Side hotswap:
PCB Header (Amphenol FCI Part: 51915-101LF)

pci-e connectors: (18awg 7.5A 30 Deg C max temp rise 32.2 max per pin)
Molex 6 Pin pci-e connector (Molex part: 0039281063)

Connectors to connect to pcb via wires
6 Pin PCI-E Male Connector (Molex part: 0039012060)

Crimp pins for 14-18awg wire:
Crimp Pins (Molex part: 0039000038)

the two solder jumpers are for power and fan speed

Also I would recommend using 2oz copper if you make one

Updated Changes & Library File
Charles Lakins • 07/01/2016 at 19:48 • 0 comments

Updated changes to accommodate pins for both spacing and hole sizes
Library Footprint Changes
Charles Lakins • 06/30/2016 at 14:20 • 0 comments

well the first rev3 arrived from oshpark , however the pci-e footprint needs adjustment
and the hotswap connector holes need to be more oblong for the blade pins as there more shaped like sewing needle heads or spears
Awaiting the new correct connector to compare its design to before changing that again
Breakout connector found
Charles Lakins • 06/23/2016 at 19:31 • 0 comments

Breakout side Connector was finally found its part numer is: 51915-101LF
However the MOQ is 200 units from one of Amphenols Re-seller distributors
Data sheet attached

Have been sourcing the correct part for the supply connector and Amphenol North America are getting back to me soon with the actual part number from the Asia Pacific branch that was the one who supplied them to Delta Electronics
the supply side connector here: (Pwrblade FCI 51939-104LF) http://www.digikey.com/product-detail/en/amphenol-fci/51939-104LF/51939-104LF-ND/5200275
data sheet attached to files
DigIkey pointed me to the wrong hotswap connector
Charles Lakins • 06/15/2016 at 23:55 • 0 comments

the board files wrong for the supply for the connector, as well as the part listed
when i showed the pictures of the supply digikey pointed me to the one i used in my design, today the supplies arrived and it doesnt fit by a mile its too long and spacing is off
online it looks the same and i idnt have a supply here to verify the measurements that wasnt in use
Board size reduction
Charles Lakins • 06/14/2016 at 19:33 • 0 comments

Another Library update to reduce outline of connector (rev3a)
Also made board smaller for reduced production cost
Library Footprint Fixed
Charles Lakins • 06/08/2016 at 19:51 • 0 comments

The oshpark link is ok now to produce, the mounting tab holes were too far from the pcb edge to align with the pins too,
If you produced a board by chance you can snip off the pcb insert tabs and it should still work ok, Ive updated the oshpark link and libray file
Under Dev - Dont produce any osh boards yet
Charles Lakins • 06/08/2016 at 01:40 • 0 comments

Im awaiting the oshpark boards in hopes the footprint is right, so hold off ordering boards until I can verify fit of the main connector
Fingers crossed its right due to the fact its $31 and change for three boards to find out it was a wasted run

Step 1

Solder components plug in wires and connect power cable to powerup :P

Is there any way to adjust output voltage on theese ? I have two and I need to get 13,7 Volts out of them to supply cars while programming.

Are you sure? yes | no

Hello, will anyone have the diagram of dps-1520ab? I need to repair the circuit where the ice 2a180z is and the zener diodes are disintegrated.

Are you sure? yes | no

I'm building a server cluster box and have 2x HP 412138-B21 2250W Redundant Power Supply Unit for BLC7000 with what I think is this male connector FCI 51939-183LF or 51939-186LF.

https://sites.google.com/site/hpc700012vpowersupply/

Having a bit of trouble finding the receptacle, female socket to the above male header. There are so many designs and the data-sheet doesn't mention the part. Trying to find the female part is a nightmare on digi-key and mouser...... :-(

contact Amphenol FCI and they will help using the online chat feature

then the same goes using digikey also for finding it if they have stock that is

they require a large min order quantity though if not in stock

there are premade ones for most supplies here

Thanks for the info. Will ask about the interface tomorrow. I've already been to the bitcointalk page but nothing was produced for the 2250w psu as far as I could tell.

Are you sure? yes | no

After looking at a few data sheets and ordering the wrong connector
(cough) I got a reply from a few emails to Mouser and FCI with (hopefully) the right part number.

Mousers postage cost to the UK is a killer so I'll have to buy a few connectors to make it worth it. Mouser Part No: 649-51915-072LF
I bought 8 pin pci-e power connectors for my DIY cluster power board to spread the load over the cables.
Now I need to learn how to use a CAD program...... sigh and find a UK pcb producer. I'm clueless.... Any reccomendations?

Now dusting of my copy of Eagle....
