HI,
Im new to this forum so thought wil start by sharing something on the forum. I dont know if there exists a post on this. None the less i'll share it.
Yesterday I went though the cricuits of an SMPS i ripped from a PC and figured out how i could switch it on. If you have used one you would have realised that it doesnt switch on when you connect it to the power source!!
So, to switch it on all you have to do it to "ground the ground". As in, connect any one of the "black" wires to the "green" wire. This will make your ground (black wire) grounded (earthed, 0V) and so the SMPS switches on. To switch it off simple remove the shorting.
Well why one would want to use an SMPS?? Firstly, its easy to use. Next, I dont have to bother about over heating my power supply (which i would have to if a had a home made power supply). Next, I have 5V, 3.3V, -5V, 12V, -12V which i can use.
I find it convinient to use an SPMS.
Cheers
