    Uninterruptible power supply for home?

    Could anyone advise what I should be looking for in a UPS for the home?

    I only want it to run a router as I quite often have short power outages where I live and its playing hell with the DLM on my broadband. All it needs to do is run a router and not introduce any electrical noise on my phone line. I dont know if they have fans or anything, but it needs to be silent.

    Any advice or recommendations?

    Cheers

    if its just for a router the cheapst one you can find tbh. they also filter the incoming electric, not that it matters as routers run via a DC psu

    i had one of these at work

    http://www.scan.co.uk/Products/APC-B...0V-Output-230V

    running a desktop and a couple of other pieces of equipment it would last ~10mins

    there is a nice piece of software than monitors the UPS

    more than sufficient to protect against brown-outs.
    there are larger versions available scan

    Re: Uninterruptible power supply for home?

    Three types, in order of performance and cost:

    Offline - normally runs off mains, if mains fails an inverter cuts in powered by the battery and supplies power. Provides some protection against surges, but takes a few milliseconds to take over from mains failure.

    Line interactive. Better performance, inverter runs all the time and supplements mains supply. Takes over when mains fails. Faster changover.

    Online. Inverter runs all the time and supplies power to the device. Inverter is fed by mains supply and battery. If mains fails, battery continues seamlessly. Best protection.

    For home use, line interactive or off line is probably the one within budget. For a router a 350VA line interactive will be fine, and will cost around £50.

    You might get an offline for less. Likely makes are APC or Emerson-Liebert.

    Yes, that is an offline UPS. The changeover is 10mS, which is half a cycle of mains power. That would be suitable for home use, although line interactive would give better surge protection.

    Re: Uninterruptible power supply for home?

    hmm, but the line interactive is a quicker changeover as well though? I just want to do my best to ensure the router doesnt lose power during "blips" lol

    Line interactive here

    http://www.liebert.com/product_pages...x?id=249&hz=60

    Changeover time between 2 and 6 mS (between 5 and twice the speed of the offline)
