Why use UPS: Because You Never Know Your computer is subject to numerous power disturbances, from surges, which can cause hardware damage, to blackouts, which can cause data loss. An Uninterruptible Power Supply (UPS) is a necessary part of your computer system, because you never know when power disturbances will occur. In such an event, Frontier's UPS devices will automatically switch your computer to battery back-up power, allowing you to work through brief disturbances or shut down your system during prolonged cuts. Your UPS is designed to keep your PC supplied with power for about 15 minutes, enough to give you tome to exit all programmes and close it down safely. However, if you frequently leave your computer on while you are away, it would be wise to acquire auto-shut cables and software at a small additional cost. With this installed, your computer will know when the power goes off and will complete the shut-down procedure on its own, without any input from you. In case you need back-up power for more than one computer and are unsure what size UPS to acquire, apply this simple formula: divide the UPS capacity in VAs with 350 for each system with 14" monitor. Thus, a 1000VA UPS will provide back-up for: 1000 divided by 350 = two to three computers with 14" monitors. (There is no allowance for printers, scanners and other "extras" in this formula!) Since monitors devour power, every extra inch of monitor size will significantly increase your UPS capacity needs! |
