Since I already have a station power supply, with a pair of deep cycle 12
vdc batts floating across a 35 amp power supply with a blocking diode in the dc plus lead, I am thinking of getting a 12 vdc to 120 vac inverter on the battery output...to feed two desktop pc's plus two lcd monitors. For the past couple of years I have used an APC 1500 ups to feed both pc workstation and also am thinking of just getting another ups to feed the second workstation...if an inverter proves to be now the best way to go. Before I re-invent the wheel, am wondering if anyone has done this before...thanks |

I would use a separate APC for each computer, and use the APC to charge
the batteries, also, they will switch back to AC once the power is restored in time, or when you start up your backup generator, plus they supply better filtering than most dc to ac converters, unless you get one with a true sine wave output.

I'd run the inverter thru your UPS in hopes it would filter or nullify that peak which one fellow measured at 600 volts here(for a millisecond or less) Yodar Yodar |
