Only few companies have UPS units at all. One actual computer store, Home Depot, and Kmart sometimes. Tried the ones they offer, and none handle the power. Tried to order online, but many shippers don't support Alaska/Hawaii/Guam. And then might get the same results from a very expensive UPS. College would get UPS units for each machine, and would work most of the time for about 6 months, and then would start having issues. Once did work for Mobile Oil. They has a $12,000 UPS for there Baby 36, and you could constantly see it switching. If freq was off 1/2 cycle it would switch, and had a narrow band for voltage. They also, had an auto generator on building. But that even failed them. Had two hour load sheading outages after a typhone. UPS could handle 4 hours, and generator would kick in to keep it charged. But had 1 guy that refuled generator. He was off for some reason, and generator ran out of fuel. UPS handled that next two hour outage, but the next ones didn't get enough charge and it died.
