Hi there fellas. I need to get a 36 volt transformer, AC, ~80 watts for a power supply that I am building. The supply will function via a linear regulator (LM338K) Wile I know that it can release ~5 amps, datasheet says it can do more w/ proper heat sink and adequate timing. I will use some form of microcontroller (eg. pic) to alter the voltage and regulate current via transistor. But that's besides the point.
I want to know where I can find a powerful transformer that would be able to supply me with >60 watts of power @ 36 volts. I tried looking at the microwave transformer, but I was afraid that it would kill me, so i stopped there. Honestly I don't really know much about AC, but really just need some supply from my wall. I am superintendent in the building here in NY so people thow lots of crap out, so I want to know if any particular appliances may contain such a powerful supply. Or is it worth just buying a supply? Or is it better to use three 12v supplies and connect 'em via serial (is it OK?)
Anyway, thanks much!!!!!
