+---- Thread: Power supply for coding/programming (/showthread.php?tid=21451)
RE: Power supply for coding/programming - Kentener - 06-09-2022
Yes, if a consumer draws a constant power, that is already the case.
I'm talking about a car with the ignition on and a half-full battery. Does anyone here really think that the current drops when I turn up the voltage on the power supply unit?
RE: Power supply for coding/programming - PhreakShow - 06-09-2022
Unlikely. Even a slightly higher voltage will very much increase the current into the battery. The drop in current due to step-down converters will be orders of magnitude lower and not detectable in this scenario.

Thank You!

I also went the way of using server PSU (HP HSTNS-PL11, to be more specific - it needed to shift up the OP to get 14+V). Some 1-1.5kW are possible to get for few bucks and with more or less slight modifications it does the job.
RE: Power supply for coding/programming - slackers - 08-09-2022
That's currently where I'm at - I'd like a slightly easier model that requires less modification as I'm a total newbie when it comes to soldering.
RE: Power supply for coding/programming - c3cilka - 08-09-2022
You don't need to be no way near "pro in soldering", it requires just few touches with soldering iron.

(at least for the modifications) There is also another step, to add some thick wires which also need to be fixed to the power supply somehow. For such thing I would prefer lugs and screws but many others chose to just yolo it and solder them.Because the mentioned HP PSU has quite small pads for lugs I end up using QS8 connector which is soldered directly on the pads.

Do you have a link to the QS8 you used?
Just Googled but can't see how they would solder to the MB.

i have 4 DPS-800GB A for sale, capable of 80A at 12V. Easily converts to 14V and up.
RE: Power supply for coding/programming - HansPeter - 14-09-2022
Just wondering: Would not a USV be enough?
Like:
APC Smart UPS C 1000 USV - SMC1000IC
RE: Power supply for coding/programming - slackers - 14-09-2022
That outputs at 240v/110v depending on which country you're in - ideally for BMW Programming you're looking for 13.8-14v.
