So what is a recommended UPS based on lack of repair experience?
Say around 1000W and say around $150 new. --- news://freenews.netfront.net/ - complaints: --- |

Thanks for the laugh and Merry Christmas. G² Bah Humbug. (It's the season so I can do that). Recommending a generator is one of my standard replies. If the load can tolerate being down for the time it takes to start the generator, then above some number of kilowatts, a generator is cheaper and better. However, if the load needs to be up 100% and can't tolerate even a few milliseconds of downtime, then a UPS is required. For loads that need both fast switchover, and long run times, both a UPS and a generator are best. For example, the local PSAP (public safety answering point) has a rather large bank of batteries and a very big UPS system, which will run most of the emergency center for maybe 10-15 minutes, long enough to get the generator started, synchronized, and stable. For my self at home, there are only a few things I want to keep powered up in the event of a power failure. Mostly the internet stuff and one laptop and monitor. All of those now run either directly from a battery at 12V, or from a small DC to DC converter. No UPS needed. (Edison was right. DC rules). Unfortunately, I have a few things that insist on AC power, so I have a small UPS to run my desktop. That will eventually go away as I switch to small computahs. Anyway, my point is really that the quality of the answer largely depends on the quality of the question. -- Jeff Liebermann 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 |

I'd pick up some steaks, beers and good smoke and go see him if he wasn't two ****ing thousand miles away in that other planet they call Cali****ingfornia. I don't see how he can stand it there. Alot of people are moving to Arizona from there where the jail inmates wear pink panties. Less crime. But the weather is better than Arizona, where if your car breaks down they find skeletal remains of your body. If you haven't been to the dentist they ID you by the VIN on your car. But that is going to change. A good piece of that coast is about ready to drop off into the ocean. Actually they should try to help global warming in California because then instead of losing the whole state all at once, they will just lose it a little bit at a time. Now up here when your car breaks down the meat is well preserved. Kinda like Canada. See, we got the best of both worlds, zero to one hundred almost every year. Like living in Africa and Antarctica at the same time. You think health insurance costs ? Try heating and cooling a house in Cleveland ! That's why the Rothschilds ad Rockefellers don't live here, they would go broke. And they ain't stupid. (what did I just say there ?) |

Standards committees were invented well after Judaism. Therefore, spell it any way you find convenient and nobody will complain because there is not one true correct spelling. At any rate, Lieberman has alot of good knowledge and experience and is not stingy with it. Any rate? I have only one rate. I charge $75/hr no matter what I'm doing. Also, do try to spell my name correctly. There are two "n" letters at the end. One is a spare in case I get rear ended. With the exception of a couple of assholes, nobody here has anything but good to say about him. I presume you haven't seen some of the email I receive. The most common accusation is that I tend to "humiliate" people. I don't really like to do that, but it works so well that I can't resist. I'd pick up some steaks, beers and good smoke and go see him if he wasn't two ****ing thousand miles away in that other planet they call Cali****ingfornia. I think my last steak was about 10 years ago. I don't do beer or booze because I'm excessively sensitive to alcohol. Smoking killed my mother and several relatives, so that's also out. Fortunately, I have other vices that can be accommodated and do accept bribes. At the last neighborhood road committee meeting, we ran an informal survey of where everyone had previously lived. I came from Smog Angeles. The rest were from the north-east or great plains. No locals. California is the standard destination for everyone. I don't see how he can stand it there. Alot of people are moving to Arizona from there where the jail inmates wear pink panties. Less crime. But the weather is better than Arizona, where if your car breaks down they find skeletal remains of your body. If you haven't been to the dentist they ID you by the VIN on your car. I live in the mountains. That's now the low rent district, with lots of owner occupied to rental conversions. Anyone that can't take it or fit in, usually moves out after the first winter. Those that remain are better than average neighbors. But that is going to change. A good piece of that coast is about ready to drop off into the ocean. Nope. The big one is going to raise parts of California. There are people paying taxes on land under the sound end of SF Bay just in case the quake produces some new dry land. Actually they should try to help global warming in California because then instead of losing the whole state all at once, they will just lose it a little bit at a time.

(Hmm...that has a nice ring to it) That plus a new set of batteries comes in at $100 or so, and you'll have something pretty dependable IME. The IBM-badged ones go cheaper than the (afaik otherwise identical) APS SmartUPS 750s.
