That implies the you're consuming 1200 watts from your 24V feed, getting 480 watts for your 12V, while burning 720 watts in the converter itself.
You sure about those numbers? It might be, but something sure sounds wrong to me.
Nope, but that's why I ask. I understand V = I x R.
The 24v+ coming from my alternator goes through a 50A circuit breaker beofre getting to the DC-DC converter. So, I assume that's the max that I'd be sizing for. I honestly don't know how many amps the 24v Delco alternator puts out.
My DC-DC converter puts out 40A at 12v per the spec sheet.
