[QUOTE=joeavaerage;2512696]Hi,

60VDC 600W would be adequate, but 80VDC and 1000W would be better. These large power supplies are expensive and most people buy switchmode supplies on the basis
of cost....but they are not the best choice. Linear supplies are far more rugged and forgiving of overload.

Craig, if you have the time and interest....would you mind elaborating on this subject a bit? How and Why are they more "rugged'? What makes them superior to a switching PS?
