Several power problems like power failure, voltage spike and sag, brownout, over-voltage, harmonic distortion have given birth to a device called UPS, which proves to be a perfect solution for all the above mentioned power related problems. As we all know necessity is the mother of invention and a UPS is just the perfect device to prove this. An uninterruptible power supplies provide emergency power backup to all the connected equipment through a separate source at the time of sudden power break down or during any other power related problems. A UPS is generally used to provide uninterrupted power for short duration of time i.e. until an auxiliary power supply is turned on or the equipment is safely shut down.

The use of UPS is not restricted for any specific equipment but it is generally used to protect equipment in which an unexpected power disruption could cause serious business disruption or data loss like in computers, data centers, and telecommunication equipment. There are less expensive methods also that can be employed to provide certain degree of protection to computers during power problems but none seems to be as effective as a UPS. UPS is considered as the ideal way to provide backups during power disruption. Without a UPS it is really difficult to operate a single computer as it can cause severe damage to sophisticated component of computer and also valuable data can be lost in case of sudden power break down.

A UPS comprises of rechargeable batteries that helps them to supply emergency power in the event of power failure. There are times when the power failure duration is longer than the battery support time then the UPS signal the server to properly shutdown and return to operation when power comes back after a proper shut down. Not only this but other power related problems can also be reduced with the UPS circuitry. Power failures and power related problems can seriously cause severe damage to systems and devices thus protecting them with UPS will prove to be beneficial in the long run.

There are many benefits of UPS that can be easily achieved apart from providing power backup in the event of power failure. Some of the other benefits of UPS include:

• Data protection- UPS systems provide enough battery power backup for saving data before safely shutting down a system.

• Protection of Computer sophisticated equipment- UPS systems are quite expert at identifying any sudden rise or drop in voltage levels from power surges thus saving computer sophisticated component from potential damage. UPS systems also prove to be beneficial in tackling power surges from lightning.

• Maintaining continuous IT systems operation- Latest UPS systems provide protection from numerous power problems to keep running the critical IT operations.
