I modified the power supply as mentioned. Maximum voltage and ovp 15v. At the moment I have a problem that when I connect the source to a 12V load the source does not turn on. Does this happen in yours? If the load already has 13v, the source will not turn off.
I couldn't push mine to 15v... The max output without load is about 14.2v if I recall correctly, however at 14,2v I cannot make it turn on. At 14,1v it works ok. I didn't had any problems switching it off... maybe you should play with the max voltage. They are not designed to work that high. Keep in mind that even the capacitors have a pretty low voltage rating. Check them out, but I believe they're rated at 15-16v so it's better to stay below.
@@alexdragomirescu5084 I connect with 14.2v in load with 12.2 car and power supply entry in poweroff. If I drop voltage to 13.3V in power supply supply start fine and now I go to 14.2 without any problem. Do you have email?
@@nitruz99919 You have to find the right settings for your power source. The important thing is to be stable. When you are working with ECU's the voltage is not that important. Bmw is asking for 13,5v if I recall correctly, so you are covered. There's no need to go over 14v. Play with it and find the sweet spot.
Só you didn't change the ovp right? When I say it doesn't turn on, I mean, the source is on and I connect the cables to the car battery and it turns off. It looks like it goes into protection. Then I have to remove the cables and lower the source voltage from 14.2 to 13v ( I have other potenciomer) and I can now connect the source.
@@nitruz99919 exactly. I didn't removed the ovp. That's the reason why at 14,2v without load goes in protection. When you put a load on it it goes just a bit under the ovp threshold, then powers up. I suggest you leave the ovp stock, to protect the capacitors. Otherwise you have to change more components inside and you saw the amount of electronics inside that thing... it's a pretty serious equipment so leave it alone.
@@alexdragomirescu5084 yes I found some videos but none with this specific power supply... I wanted this 1400w version and only find videos of the 1200w version...
@@cavidoman Don't worry it's the same setup ;) once you've open it you'll figure it out. They are well protected electronically so unless you do something really stupid you can't burn it. However I do suggest you take good care when working next to the input line capacitors because they do hold high voltage even when unplugged.

Hi! DID you modify the supply on your own?
Hi, yes I did. Normally it's stabilized at 12v. You can find the mods on internet however. Good luck!
@@alexdragomirescu5084hello, could you please provide the link where you got the instructions to do this mod? Thank you 🙏
@@cavidoman hi, there are other videos here on RUclips that explain way better than I can. Search for HP DPS 1200. You'll find more results;)
