Has anyone figured out how to adjust the output voltage of a Dell Poweredge 2850 power supply, model 7000814? I just converted a couple to be charger power supplies, but would like to be able to tweak the output voltage.

Along these lines, I have been able to isolate the output from the chassis ground by going inside the box and remounting the two circuit boards to the metal chassis with nylon 4-40 screws with nylon washers between the boards and the chassis mounting ears. Then I can use them in series.

Anyway, I'd like to be able to tweak the voltage of the supplies. Can anyone describe how to do this for this model of supply? I searched the thread, and it seems that connecting pin A2 to +12V through a resistor (say, 470 ~ 1K ohm) puts the output at 12.5V, but it would be nice to have finer control than that.

Thanks in advance.
