Re: [AFMUG] DC question

[Roland Houin]

It certainly would work. I've done it to eliminate conversion at the top.   roland   > Yeah, running 48v to the top and then dropping to 24v is what I was planning on doing, but I just got to wondering if the other way would work... the only real advantage being less electronics at the top.

DC doesn’t lose much voltage over even a 1000 foot run of 12 gauge. What happens is the wire isnot heavy enough to carry the needed amps. There are some calculators that say how many amps a certain gauge of wire can carry at such and such voltage on DC. Most folks we work with are running 10 gauge wire up the tower in these cases.

Depending on how far you are running it, I would recommend doing 48v also to prevent voltage drop. I am not sure you can even do waht you are asking if you are using something like 16-3 service cord. That goes beyond my knowledge. I would personally down convert to power two different pieces of equipment.
