UPS's come in different sizes depending upon how many computers or equipment you want to plug into it. For example, you might want to hook it up to your computer, monitor, modem, LAN router/hub. In that case, you would
want a UPS with a higher rated power output. Depending upon the UPS's rating, you can typically run on battery power for no more than 30 minutes before the UPS's battery becomes drained. This should be plenty of time to get you through any brief power
outages or to safely shutdown your computer.
Note: Unless your UPS has a high rating, you usually cannot run a laser printer on battery power since the power requirements of a laser printer spike up when its print mechanism turns on
when you print a page.
Note: Typically after 3-4 years the battery in the UPS will wear out (it will no longer hold an electrical charge) and needs to be replaced (the sealed lead battery must be shipped to the
manufacturer for proper recycling). Typically the UPS is designed to perform a self-diagnostic every few days and report any problems. |
