fenderstrat,

The pic you posted are from my PSU. Thats what I was doing to power on the PSU. I tried rcnut's pin connection layout with a 560 ohm resistor and it also works fine. Actually eliminates jumping the two tabs.

hhhmmmm,ok the pic I was SENT shows a resistor between pin 33 and ground.So it seems you need to do different things for different models.as I said, I'll just have to get some resistors and do it with some old fashioned trial and error

RCNUT,you have the resistor between ground and ? what is the V reading on that tab.
No...my resister is not connected to ground.

I borrowed this picture from you;

I did not wire mine like that. I placed a 220 ohm resister between pin 33 & 36. I'm thinking pin 36 (according to the print) is a logic pin looking for some voltage to turn the supply on.

In the picture above...the 560 ohm resistor could be acting as a load for this switching supply...or could simply be a means of turning the LED on.

Sorry for any confusion I might have caused.

ok,I do appreciate all the help.

just to clear up the confusion the PS I have in front of me is the one pictured by ARdB.the pin layout is different than all the others I have seen and there are NO indications of any tab numbering(of course..lol)

The picture and schematic that I posted was sent to me by someone,and his is showing the resistor jumping a tab to ground(similar to the ATX style I have here now).it also seems to have a pin layout similar to everyone else's.

You guys are saying that you got yours running, but NOT grounding a tab.

and I think I just fried one of the ones I have here by experimenting,but its no big deal as I have access to a bunch more.

I am determined to get this to work now just out of principal and me being stubborn.There are only so many combinations that are possible.I'll get it, I just thought this was going to be a little easier.If I could figure out which tab is "power on" we are in business

oh and 1 more question,should I be using a 220 or 560 resistor?

Start with the 560 to 1K resistor. The only thing you could burn up is that little resistor, vs. a wire jumper.

thanks.

I am going to head to radio shack in a little while.

I am going to spend my friday night trying to get this PS to turn on...and I am exicited and looking forward to it(my new PL6 is on its way).Am I a heli geek or what

DSW, FYI...the other side of the circuit board, the plus and minus pads are connected. The negative and positive big copper pads are zero ohms.

So if you want to use two heavy gauge wires for the negative and positive, you can solder one negative on one side and another negative wire on the other and tie them together!

If you have the same type of supplies I do, the output is rated for 100 amps at 220Vac, 75 amps at 120Vac.

i just finished making a mobile charging station has two Dell server PS running at 12.9 volts 43 amps each and tied together puts out 25.8 volts and 1100 watts going to a Cell Pro Power Lab 6 which allows it to run very near it's full capacity if needed !

it's the last one i'll ever need......

good news and bad news.

the bad news is the dps-700 just will not power up,but I'm gonna try some more

the good news is I also have a dps 800gba and I got this model to power up and put out 12.15V.I have not put a good load on it yet but it looks as if it will work just fine 69.9A at 12V should be plenty...now if that PL6 would just get here

I was wondering the guys with the 1200 systems. What is your voltage reading?

I currently have 2 in series and I am getting 12.2v for a total of 24.4v. I was hoping to setup this up to see if I could get a little over 25v.

25.8 volts on mine, there was a place for a jumper on each of mine that set the voltage a little higher......

Last night I charged all my pack for todays flights, and was pulling 40 Amps out of those supplies...total.
