WHAT IS A UNINTERRUPTIBLE POWER SUPPLY (UPS) ?
An Uninterruptible Power Supply is a device that provides battery backup when the electrical power fails or drops to an unacceptable voltage level. Small UPS systems provide power for a few minutes; enough to power down the computer in an orderly manner, while larger systems have enough battery for several hours. In mission critical data centres, UPS systems are used for just a few minutes until electrical generators take over.
The most common reason for UPS failures is their batteries. UPS batteries need to be consistently maintained to provide the maximum reliability. The ideal environment for UPS and Battery systems is one that has automated temperature control together with a 24/7 or remote monitoring device.
