I have 25 locations spread out over a large area we recently had another power outage lasting 48-72 hrs.depending on the location. all locations have UPS back ups with generators. Problem:
- The ups does not last but 6- 8 hrs. All equipment runs on 24 vdc. at about 3-3.5 amp stedy draw.
- Generators are running for days to power a PLC. I have people running around check generators round the clock.
I propose remove UPS and install 2, 12vdc lead acid type batteries in series 200 amp hr.each to power the system. So the system runs off the batteries 24/7 this should have a smooth current out flow immune from spikes??Yes/No?? I also need to be charging the batteries all the time?? I hope to size the batteries to last 72 hrs or more. Can this work?? Benefits no expensive UPS ours are pricey, no wear and tear on the generators, no fueling the generators during the outage, no people checking operations round the clock during outage. need a solution.
