Hi there,
I am looking at creating an AC/DC Power supply to output max 3Amps
I will be using a (UK) 230v - 2 x 24VAC 3.2VA Transformer. Just want to also know does this mean it will give me 3.2VA per 24VAC secondary winding ?
I need to know what diodes I can use for the bridge rectifier. I have been looking at the Vishay SBYV28-50-E3. Could I put 2/3 1N4003-E3 in parrallel as these are rated at 1amp ? Would putting them in parrallel give me the 3amps I need ?
And what regulator will I need. I was looking at an LM338T. it is rated at 5amps, but is it effiecient ? Any suggestions would be great.
I need it to output at most about 19v DC.
Thank you
