The Importance of a UPS Battery Backup Device
UPS stands for uninterruptible power supply or uninterruptible power source. This is an electrical device meant to provide power supply to a load in the case of a power outage or when the power input fails. It differs from an auxiliary or emergency power system or standby generator in that a UPS device provides instantaneous (or very nearly instantaneous) protection from power outages.
At any moment and for any reason, power supply could be suddenly cut off. Power outage can result from electrical poles being damaged by storms or traffic accidents. Faults in the grid or power plant can also cause blackouts. Or there simply may not be enough power supply in a particular area at that time, so power outages are scheduled. We have learned to cope with these inconveniences but our computers, unfortunately, just are not hardwired to cope with them in the same way.
Sudden power loss during data transfers can damage partitions making the hard drive inaccessible.
Computers are fragile pieces of machinery which can be damaged by a sudden power outage or fluctuation. Items in a computer like hard drives can be affected and data can even get lost when power goes off and you have not properly shut down your computer.
It is especially damaging to the computer hard drive when there is power interruption. When power is suddenly cut off, your hard drive spins down without being shut down properly. When power comes back, and you restart, at times you may find that much of your work has been lost. Sudden power loss during data transfers can damage partitions making the hard drive inaccessible. Also power comebacks usually are accompanied by flickers or fluctuations which may turn your computer off again. Hard drives can only take too much of this type of abuse. There are some cases where computers even blow up.
To protect your computer hard drive from these unfortunate scenarios, you need to plug your computer into an electrical device called a UPS system. Right at the moment of a power blackout, these nifty devices will act as a battery backup power supply which will automatically provide power to your computer for long enough to allow you to save your data and properly shut down your computer.
A UPS device not only protects your computer from lack of power, it also protects from too much of it. A UPS is also a surge protector in that it shields your computer from those little brownouts or flickers which we do not notice but which can wreak havoc on your computer.
