300W tiny PSU final feature requests collecting
this project is continuing abd aim to a 400W tiny one.
to read the Q&A please jump to page4
it is here:http://www.mp3car.com/vbulletin/show...7&page=4&pp=15
the brand new design of my 300W tiny PSU is going to be manufactored soon
please post your feature requests here, to make it suitable to more users.
1.up to the design, the output could be as follow.
I know that the large the better, but the price(not the size) will be related to.
12v main 12A? 15A? 18A? 20A?
5v main 10A? 15A? 18A? 20A?
3.3v main 10A? 15A? 18A? 20A?
5v standby 1A? 2A? 3A?
-5v 1A? 2A? 3A?
-12v 1A? 2A? 3A?
2.the shut down controller can be user upgradeable
anlogal shut down controler
digital shut down controler
mutifunction/re-programmable digital shut down controler
8v to 18v ?
8v to 24v?
8v to 30v?
what should the lowest input votage be?
6v to 10v (notice, at 6V/300w, the input current would be over 50A!)
according to the design, it could be fanless under 200w at 45 degree C condition.
if someone want to mount PSU near the engine.....
5.technologe used on this PSU:
full indepandent channels for all output votage
high quality import parts even the powdercores
ATX standar logic
6.should be decided:
the INPUT wrong wire protection.
as the input currency could up to 30A or more at some conditions
if added, it will low down the efficency
if not, wrong connectting + and - will burn the PSU....
