| 666616 | 2008-05-07 01:52:00 | A Basic UPS doesn't have to be expensive - I use these all the time (www.ascent.co.nz) - this one is from Ascents advert. They work perfectly fine - Only had two fail in 5 years out of the approx 100 I have sold. 1st one blew because the Person had a massive power surge in the house, it blew the TV, Microwave, DVD player and stereo - The PC survived because the UPS simply committed suicide because of the Surge was so great, it is designed to do it - PC was saved. (and the manufactures replaced it under warranty) 2nd One blew because the building HAS still got a wiring fault, the UPS would be triggered at least 5 -6 times a week, esp when the hall attached to the building was being used by the church group - it lasted a year and a half before finally saying ENOUGH :lol: BUT the PC was saved. (they still wont get the wiring fixed though - so the second one will last how long I dont know) A direct lightning strike will fry just about any protection. |

That looks like quite a nice unit, and probably an essential for any business wth todays ower problems . How long can it run a basic computer and LCD for, after the power goes off? |

| 666618 | 2008-05-07 02:03:00 | That looks like quite a nice unit, and probably an essential for any business wth todays ower problems. How long can it run a basic computer and LCD for, after the power goes off? Depends on if any programs are working, or how much work the PC is doing at the time, what drain is on the UPS battery from the Hardware in the PC, or if its not doing anything, BUT generally around 25- 30 minutes. When doing some wiring here a few weeks back the ones in the workshop were still beeping ( like a truck backing beep) indicating no power 45 minutes later, still going strong. I have had customers comment that ( and I quote) the Bl00dy thing was beeping for hours until the power came back on. - Dont know if that was exaggerated or not. They are not designed to keep the PC running for a long time, only to save any work, and shut down safely. OR in the event of a brown out (Power Drop) kick in until the power comes right again. They are designed for PC use, not like some people who try and connect heaters to them and wonder why the overload trips. |

| 666619 | 2008-05-07 02:12:00 | EVERY Electrical appliance that was plugged in in his house got totally fried, the Insurance company had a bit of trouble believing it had happened. Totally fried is good, many insurance policies won't pay for electrical failure unless actual burning out occurs. Mysterious failures become manufacturer's warranty issues |

| 666620 | 2008-05-09 03:17:00 | Of course a typical surge protector won't protect for many/b] surges. :D The MOVs which absorb excessive energy are damaged to certain extent each time they are hit. A major surge will destroy the surge protector. The items it "protects" [b]might survive. If you know there has been an "event", replacing the protectors is prudent. A power "blackout" won't hurt equipment. What happens as the power is restored might. If the power comes up. drops out, comes up again, it can cause curent surges in the PSUs. |

| 666624 | 2008-05-10 03:28:00 | Basic At the bare minimum, you should use a good surge-protected multiple-outlet power strip for each computer . There are a number of products on the market that provide excellent protection and at a cost of less than $50 . . . . . . . . . . Of course a typical surge protector won't protect for many surges . :D The MOVs which absorb excessive energy are damaged to certain extent each time they are hit . A major surge will destroy the surge protector . The items it "protects" might survive . If you know there has been an "event", replacing the protectors is prudent . . . . . . . . the problem with this type of gear is virtually noone does testing to say if your $200 surge protector is any better than a $10 one . consumer mag did a good test many years ago, it was supriseing how bad most surge protectors where . a lot did absoulutly nothing . i would expect a lot of the ones on the shelves today are problerly not worth having . you can be sure a single MOV $40 board is not going to do much . also for those in bad aeras, forget those fuse board MOV's, fit a diverter on the incoming cables into the house (first point you can which is usually master switch) . they only work on the BIG spikes and can save your wires from burning and things burning . |
