Which light did you use or can be used?

Hi,
6-8-10 has worked on 3 of these power supplies for me. 6 is the short pin. Some people have had problems with servo connector receptacles not working, I use JST-XH balance connector receptacles.

There is a link a few pages back to another web page with a slightly different jumper connection.

Maybe your p/s is bad? Slow fan speed on powerup is what I saw also.

Good Luck.

Also gives some voltage on #18 and when this one is grounded, 12V output is turned on. I only get 11.9V though, both with a light load and noload.
Wish pinout was available. Maybe voltage can be adjusted via some of them?

Edit:
It happily delivered 48A to my charger and voltage was stable.

Connect both X's to ground (G):

I believe you have the server model number wrong for this PS. The PS in PowerEdge 2650 is a 500W unit. Those units are very common on eBay and such. The unit you describe here sounds like a PowerEdge 2850 PS, which is indeed rated at 700W, or 12V 57A. The model number is NPS-700AB. Your pin-out works great on this unit. I have put together a how-to on my site.

The 2850/2950 dell series has been replaced by their 'n' series (n705...).

The power supply out of the N705 is a 'Z700P-00' which is about 40% shorter in size than the 2850/2950 supplies and has the exact same back side connectors (including no fan cover) :/

pretty good chances of the pin-outs matching your 2850 mod above?

looks like this one puts out 58A/700w, but that is probably at the full 240v source? not sure what it will push out at 120v.

You are correct. I have changed the server model in my post.

Same pinouts worked. But the thing is a jet engine and I doubt I'll use it.

The cooling is a bit overkill for usage in normal environments. Just turn the RPM down a bit using a series resistor or run the fan on 5V:

I don't mind the sound cause it reminds me I am charging

I found three trim pots on a circuit board in the power supply which I hoped adjusted the voltage. I marked the wiper positions with a fine marker so I could always find the original settings in case something went wrong. One trim pot did indeed adjust the voltage. I don’t know what the other trim pots do. Range was 12.6v to 13.6v.
No problem with over voltage shutdown at 13.6v.
I’ll only be using this supply at about 20A for now hence the use of only one pair of output blades.
The pictures below explain the connections.
Great thread, thanks guys.

Hi

i have 4 of those here in my desk
I did the conversion based on your pitures.
I use Junsi iCharger 106b+
Sometimes, when the PSU is running and i connect the charger, the PSU will shutdown, the other way around, it works.
Have you seen anything like this ?

Can you take a picture of the pot, where you adjusted the voltage ?
There are 3 on a vertical board inside

I also could not get the switch to work...

Most likely the current spike when you connect the charger causes the PSU to shut down to protect itself. Keep in mind even though these are hot swap capable supplies they have a soft start feature when used in a server. You should always connect the charger before powering the unit on.

Did you get the dps-460BB running?

Looks like thats the problem...
Connect the charger first ... works !

This is the first time i can use the full power of my iChargers...

Hi outlawrc.

Here's the pic you wanted.
The pot with the driver adjusts the output voltage.
Same deal here with shutdown on charger connection. Connect charger before plugging supply in.
I don't know why your switch does not work. Are you sure you followed the pinout I posted? The yellow I used for
the connections did not show well.
Hope this helps,

hubgar.

Any ideas on a dell server ps nps330bba to get it running before i let the smoke out. I have the circuit board pluged in to the ps, there are several red 5.5v, yellow 12v, black wires gnd, and 1 blue wire all, all wires are on a plug that plugs into the circuit board

Hi madatme.

I think what your describing is more of a regular pc power supply than the powerful server power supplies in this thread.
There are many conversions for the pc type. Check here.
