An uninterruptible power supply (UPS) protects electronic equipment from power outages. It is essential for servers and network equipment, but less necessary for individual computers. UPSs come in various capacities and price ranges, and it is important to consider what equipment needs to be kept running and for how long.
An uninterruptible power supply (UPS) is a battery-powered power supply that helps protect electronic equipment from a sudden power outage. It is especially useful with computers and equipment that could be damaged in the event of a power outage. In some cases, UPS battery units can be combined with generators to provide power for long-term outages in larger business environments where downtime could harm the business.
Uninterruptible power supplies are important for certain types of equipment that could be damaged in the event of a power outage. For example, computer servers are typically left running 24 hours a day, providing services and files for other computers. A power outage could damage data on a server or make data unavailable to users. In large corporate environments, network equipment could also benefit from being on an uninterruptible power supply, as a loss of power to network equipment could prevent communication over the network. Either way, an uninterruptible power supply can ensure that equipment will remain operational even if external power is unavailable, as well as reduce the possibility that a power outage could damage data on a server. In such cases, an appropriate backup power solution is highly recommended.
In other cases, UPSs are less necessary. Individual computers in your home or office probably don’t necessarily need backup power. In these cases, while backup power from a UPS might ensure that the computer is operational during a power outage, a lack of power to other devices (such as the absence of lights or other electrical equipment) is likely to make backup power less than useful. While a sudden power outage could damage data on a running computer, regular backups of a home or office PC provide protection against data loss. While uninterruptible power supplies aren’t necessary for many PC systems, small units are available for little money and can provide a measure of protection against power outages.
UPSs come in a variety of capacities and price ranges. Some UPS units are designed to provide enough power to keep computers running until they can be safely shut down. Others can keep equipment operating for hours. When purchasing an uninterruptible power supply, it is important to consider what equipment needs to be kept running and for how long. The more devices connected to the UPS, the faster a battery power supply will discharge. Unsurprisingly, larger capacity solutions with long-term power supplies generally cost more than smaller systems.
