Thus spake "Wayne Bogan" <wbogan@InfoAve.Net>
For those AC only powered units, you can also purchase an invertor for DC
to
AC conversion. You would then have the advantages of DC for your AC equipment. This does, however, add the potential of another point of failure such as fuses or breakers in the invertor.
Well, that's how AC UPS's work -- just beware what percentage of the input current is lost in the conversion from DC to AC, plus what is lost converting from AC back to DC inside the equipment. Much simpler to specify DC equipment to begin with if you really care about availability. S
