  • 12dc-dc 55w 39.50

    just found this, its ideal for my project, i have had a real issues looking for a powersupply. At this price it isnt worth making one.

    Yep, that'll be fine for any non-automotive applications...

    (sorry was nearly as sarcastic as the monkey then! )

    The problem with that is it doesn't regulate, so whilst you 'could' use that in your car, you risk popping your kit. You computer wasn't designed to take 13.8 volts +.

      Why not? did you mean the 13.8V will get fed directly to his motherboard?

      From the picture I see a mains - dc converter...presumably outputing 12V?

      Not too sure about "not worth making one" not worth making a whole PSU or just a regulator?

      Ill say stick a 12v regulator or whatever volts it require before you feed it in directly. I dont know how bad the design on those PSU as it may well be feeding the input of the PSU directly to your motherboard...in that case you will get 13.8V into your motherboard rather than 12V, you will blow it.

      Check the AC-DC adaptor for output voltage or current. Im guessing you gonna connect the input of the PSU (without the AC adaptor) directly your battery?

        Exactly. It assumes a clean regulated 12v input, and 12v line is passed through.

        Remember that as well as feeding 13.8 volts to your motherboard all the time, you could also be sending +/- 300v to it when you stop your engine due to alternator dump!

          Hi,

          Thanks for pointing out that.... im a newbie and obviously a little green. Would not putting a voltage regualator between the PSU and the battery solve this problem. Is that not essential that every type of PSU would need this voltage correction because it seems inherent to the nature of the environment.

          Does anyone know of a 12v Regulator which is appriate for this solution?

          Cheers,

            I have a linear regulator before mine at present, the circuit I built is on my website at the URL below.

            Works okay, but only when the engine is running. Thus I'm now getting an Opus.
