    Default Surge protection

    Is it worth getting a U.P.S to cover surges than say just a power surge protection board
    do you members who have web pages and prints for sale use them ??
    are they effective for the outlay.

    A UPS is probably more effective than just a surge buster, brown outs and voltage dips can do more damage to a computer than power spikes and in some areas are more common. They do work but you need one with enough capacity to run the computer for a few minutes till you can power it down.

    Thanks Chris, we have already lost one monitor to lightning hitting a tree up the road, with just a single surge protector you only get one save, with
    brown outs and dips not many people realize how bad they can be.
    just wait untill there is a run of hot weather and everyone turns on the air con , then the power guys do a rolling black out, to bring it back and save output

    Definitely recommend the use of an UPS to protect your gear from 'dirty' power (power spikes, dips etc). Just be sure to check the specs and ensure you get one that features AVR (automated voltage regulation). Many of the smaller, cheaper units don't feature AVR and thus aren't capable of regulating 'dirty' power and supplying 'clean' power to your equipment, so they only act as battery backup.

    Ideally I'd try to get one that outputs a 'pure' sine wave, not a stepped/modulated sine wave. Those that output a modulated sine wave may (worst case) damage certain types of power supply units in computers (those with Active PFC). At the least they may be incompatible and your PC will shut down immediately rather than work off the backup battery power.

    The product specification list will usually clearly state if it has these features.
