Hello, if I have a 20amp DC input and use a Victron DC-DC converter 12v to 24v, will the output be 10amp, as the amps will halve as the current is converted from 12v to 24v?



If that is correct, can I purchase a 10amp 12v to 24v DC to DC converter where the input is 20amp and the Output 10amp? Or are the converters sized from the Input current?

Thank you for your help
 
20A @12V (240W) input = 10A @24V (240W), the power are the same, but it will more likely to be more than 20A on the input due to conversion and system loss.
 
Hello Smooth Joey and Bud Martin, thank you for your replies, that is good news, as a 10amp 12v to 24v DC to DC converter is a lot cheaper than a 20amp one :)
