    Tips: Why we need a UPS (Uninterruptible Power Supply) for computer?

    There are at least nine problems in the power grid, interruption of power supply, lightning stroke spike, surge, frequency oscillation, voltage mutation, voltage fluctuation, frequency drift, voltage drop and pulse interference. Therefore, it is necessary to equip a computer with an uninterruptible power supply (UPS) from the perspective of improving the power quality.

    In addition, the power supply is not allowed to be interrupted in precise network equipment and communication equipment. It is self-evident to equip UPS battery backup to the network center with the core of server. Even if it is an ordinary computer, its data file and other software value exceeds the hardware value after being used for three months. Therefore, it is really necessary to equip uninterruptible power supply (UPS) to prevent the data loss.

    Very nice
    So far, everything has been fine. Now the power consumption in our area is too large, and there will be frequent short-term power outages. This uninterruptible power supply has the functions I need. The backup battery is a commendable design.

    Does ATO's UPS meet my requirements?
    I need a UPS that will provide back up power to a load of 60 watts for a minimum of 6 hours. I need 220v single phase 50hz for an Asia application. Will your SKU: ATO-UPS-2K meet that requirement? And what about if the load is 360W?

    The 2kVA stabilizer can backup the power for 60W load theaortically for 6 hours, and can backup the power for 360W load for approx 1 hour.
    Great 2000VA UPS
    I bought this about 3 weeks ago, and it worked fine to keep my computer on while there was a power outage. I have to say this was a real savior. I was very pleased with this UPS quality and functionality. Great UPS for anyone working at home or having frequent power outages.
