To adjust voltage above 12V connect the +12VRS- tab to the 5VSdBy tab through a 5k or 10k potentiometer.

Let us know how high you can adjust the voltage.


Were does the 3rd line on the pot go to. Cause on a pot there's 3 connections. I picked up 2 10k pots but there's 3 connections on it were does the third go to.

Thanks

Hey Bubba Gump,

Connect the third pot line to ground. The pot wiper has to go to the +12VRS- tab. Connect the other pot line to the 5VSdBy tab.

DELL Z930P or DELL A930P mod

DELL Z930P-00 power up mod

Ok, after few days of working on it I was able to properly power it up!!!
Big thanks to all of you guys. Special thanks goes to XANDRIOS for sending me few important remarks on what to do.
Here is the deal. The only 1 pin that needs to be connected to -12V output is pin D2
I have ON/OFF swich wired directly to the board.
That is it!!!
Works like a charm. Now I just need to slow down the fan.... And this is done now and working.

09L4299 IBM Power Supply

Help !!

I have an 'nos' 09L4299 IBM Power Supply - originally used in an IBM 7133-D40 (among others), Could not find any information other than the 7133-D40 manual - which is pretty much useless for our purpose .

It has a 9-Pin D connector in the front - supposedly for remote power control. From the drive manual I reckon only 4 pins are used in the 9-Pin D, because the other end of that link cable, I suppose, has a 4-Pin mini-Din.

The Delta p/n is: D0009245/01

Thanks,
Sparks

Hey Canucksparks.

The turn on pins may be on the back in the center pin matrix..
PSUs used in IBM systems usually have a single turn on line.
Exclude the ground, 5vsb, 3vsb and pins that show no connection to ground.
Then try connecting the remaining pins to ground/each other through a 500 ohm resistor one at a time.

There isn't much info available for your PSU.

If you get an orange light and no +12v power then go to this post for instructions.

These are solder points to disable the Over Voltage Protection (OVP) on the Delta DPS-700EB PS.

Just solder a short wire across the two components highlighted in the picture.

They reside under the white cover on the rear side of the DC-1749 daughterboard.

Be sure to solder quickly as these are small components.

Voltage can be controlled externally by using a 1k or 5k potentiometer

between pin #63 (12VS) and ground.

Maximum voltage will depend on the individual PS.

It will be somewhere from 14.8v to 15.2v.

I suggest staying below 15.0v to keep everything within spec.

You may also set the internal voltage control trim potentiometer (at bottom of daughterboard) to maximum(counterclockwise) after modification is made.

I've tested this with my PS at 15.0v with a 65A load where OCP kicks in.

Over Current Protection (OCP) circuit still works with this mod.

This is just one method to disable the OVP. I opted not to remove any components.

And as always do this mod at your own risk.
Have here a DSP-750EB A witch should be quite similar to the DSP-700EB. Unfortunately I'm not able to get past 13.5V but need past 14V.

The daughter board is labeled DC-2173 (instead of DC-1749 for the DSP-700) and has different layout. So the modification on the daughterboard shown above is not possible.

Anyone could help please ?

Thank you Xandrios.

If I exclude gnd, 5vsb, 3vsb and pins that show no connection to gnd, will there be any other pins left that are not connected to one of the above ?
And, will I be able to see the 5V and 3V on the pins without the unit starting-up ?

I have returned it to the surplus dealer . Will get it back and give it a try, though.

Thanks again for your prompt response.

Hey Canucksparks.

The 5vsb and 3vsb pins will show voltage even without the PSU starting-up. These standby(sb) voltages will usually be spread across multiple pins. Also, signal ground is usually spread across multiple pins. Pins that show no connection to ground are just left as spare pins and don't connect to anything.
The pins that are required for PS turn-on will be within the remaining group.

Hello mige0.

For the DPS-700EB mod, I just shorted the corner non-inverting input of the LM339 to ground. The DPS-750EB has a similar setup. Just look for the same smd diode. It will connect to the same pin. Shorting this pin to ground with a 1k resistor should allow you to increase the voltage to around 14.8v.

Here they are up and running in series and was able to float the grounds on them. Did the pot mod and had the single one up to 13v and a 30 amp load on it no problem. Here is a pic of a 40 amp load on them, the second pics what I'm planning on setting up with them a 2600watt setup so I can run a pl8 and pl6 maxed out all day.
