- In this video I give an update on one of my previous videos that show you how to convert a HP DPS-1200 series server power supply so it will turn on and output 12 volts. Here is a link to the original video. • How To: Converting a p...
Thank you, my friend. Go to know I do not have to waste my resisters.
Thanks for this video!! I just pulled 4 of these out of the recycle bin at work. Free 12V 75A (or 100A if using 220AC input) supply! I might design a 3d printable case for it with an on/off switch and XT60 plugs. Will link it here if I do.
Hi @izzlate , did you ever get to the 3d printable case for this psu?
What is the difference in using a resistor vs a straight through wire?
I converted mine to do 14.9 volts and 75 amps and built a power supply for my lenear amp, works awesome
Which version do you have? Im trying to convert PD19 to 14.5v but not finding much solid information.
not possible
@@mikemorgan2733very possible lol these things are beasts as power supplies for linear amps
Thank You.
Lovely guide.
Question for you I have 2 of these to make a 24 system like your other video but they will not work when connected together only individual units any ideas?
Did you follow my tutorial and float the DC ground on one of the units? And are both units powering on?
@@JoshMoenheli thanks for the reply, I figured it out and sent power out vs sending it to the slave psu.
So I swapped the power leads as direct and it still doesn’t work
After some more testing on the master I have continuity between + lead and the case
Have you tried to up the voltage?
Yes. In the other video I go through connecting them in series and adjusting the voltage up as high or low as possible.
Is it possible to decrease the voltage to 10V?
The voltage will drop down but if I remember correctly it will only drop to 10.9-11 something.
Do you remember what should be modified to decrease the voltage ?
Supposed to "float" the internals too using plastic washers. I also added rubber feet.
If you plan to use them in series that is correct. This is an update to a video I published over a year ago. ua-cam.com/video/dDPm2iB_6c4/v-deo.html
@@JoshMoenheli Ahhh, I guess I didn't realize you had this video out there. My apologies. I did my retrofit in like 2015. I'm not sure which fan mine has on it. Also not sure what the differences are between the two fans. I started watching these videos again after 7 years because I'm going to be using this power supply to bench test car amplifiers. So I wanted to see about voltage. Because car stereo amplifiers like 14.2 v. And the SPL (sound pressure level) guys push 15 or 16 volts. But one of the guys on the car audio group said 12 v. 70 A will be fine for test purposes.
Thank you man❤
Use a switch and some wire.
That's an SB not FB
