So I wish to build a variable output mains power supply as a learning exercise.
I have determined the transformer that I need and now I am looking at the rectifier bridge.
I have looked at these diodes http://uk.farnell.com/on-semiconductor/mur410rlg/diode-ultra-fast-4a-100v-axial/dp/2441588
Which should easily allow my supply to deliver 24v @ 2.5A
Am I right?
Do I need to look into protecting the rectifier from a short?
I don't see many online guides dealing with this.
Also when it comes to earthing. Should I ensure the body of the case and transformer are connected to the death pin of the 3 prong plug. Earthing 24v on the secondary coil seems overkill.
