Allthough cranking the voltage past 13.8 volts probably won't damage anything,
there is no guarantee to that, so just keep that n mind.
Aslo, for something like server supply, this could well be a Class A digital
device, with significantly higher noise.

Subject: Re: [RFI] Report on 12V 750W server supplies
I recently purchased the DPS-750RB A model, which is also shown as a
HSTNS-PD18. Using the instructions on YouTube, I easily changed the voltage to
13.9v. I haven't had time to look for RFI using an SDR, and certainly won't
have as extensive a test setup as Gary does.
I did not try to adjust higher than 14v, though that might be a good
experiment. If I had any confidence I wouldn't damage something by doing so,
I'd be willing to try higher voltages :-)

Thanks Gary. Do you know how high V+ can be set? Some radios, notably
Elecraft rigs, have lower IMD at higher supply voltages, with 15V max.
