A UPS (Uninterruptable Power Supply) is a device which acts as a power backup to equipment in case of a power fluctuation or an outage. In case of a power fluctuation the UPS is activated automatically and supplies constant power to devices for a short time as a temporary solution. The UPS protects hardware such as computers, network equipment, servers and other electrical equipment where unexpected power failures occur. The role of the UPS in data center operation cannot be understated. Power failures can be expected to occur at some time during normal operation. The data center’s UPS must have the capacity to withstand the disruption without any major effects on the business. UPS is a technology which is used to reduce the risk which occurs from power failures. As soon as power outage occurs, the UPS takes charge and supplies constant power to the crucial equipment and the work continues without any impact. Importance of UPS System. The power backup system of a well-designed data center should avoid the huge cost involved in power outages. Critical equipment must be able to endure the power failures without any damages, data corruption or downtime. Incorporating a UPS in the data center is the best way to ensure the devices safety and its functionality. When there is a power outage in a business environment the cost can be very high. The IT environment is dependent on the constant function of computers and electrical systems. When these systems are damaged and or data is lost, the operation incurs the cost associated with equipment replacement and maintenance, productivity losses from downtime, business inefficient from data loss, customer services interruption and more. Causes of power failures. Numerous events can cause power outages that require UPSs. Regardless of the causes, the result is damage to the supply grid, which in turn affects power to the data center. Many utility outages can be attributed to natural events, including lightning strikes, heavy winds, major sandstorm and other acts of Mother Nature. Other outages can be the result of accident involving animals. Trees and vehicles. Building maintenance is another cause of power outage. Many companies don’t have backup generators to use during downtime caused by damage to the building or scheduled maintenance. A UPS will provide instantaneous, emergency power when the input power source fails. During these outages the UPS runs for a relatively short time. However, UPS systems run on batteries until the backup generators, if available, takes over to provide uninterrupted power to crucial data center equipment. UPSs play an essential role in protecting computers, data centers systems, telecommunication equipment and more.
