Uninterrupted Power Source. A generator and/or battery system that, in the event of a power failure, provides power to life-safety systems (e.g., fire alarms, emergency exit lighting, and elevators). Also called Emergency Power System.
Justifiably popular with many electronics users, a UPS stores electricity in a battery and supplies power to a system (allowing a user to shut down w/out losing data or continue for a specific time period) during a power failure.
A battery system which provides power to a computer if electrical systems fail. A UPS allows a system to be shut down safely, and prevents power shortages from causing damage either to the equipment or to the information it stores.
Uninterruptible Power Supplies. Uninterruptible Power Supplies use generators and/or batteries to power themselves, keeping them operating during power outages and helping to prevent loss of service for mission critical applications.
Uninterrupted Power Supply. A backup battery module attached to a computer that allows memory contents to remain intact long enough for the operating system to perform an orderly system shutdown if a power outage occurs.
Abbreviation for uninterupatible power supply. A device containing a battery that allows a computer to keep running for at least a short time after the primary power source is lost. When the UPS notifies a user of the power loss, the user can save any data he or she is working on and exit the computer before the battery runs out. During a spike or power surge, the UPS intercepts the surge or spike so that it doesn't damage a user's computer.
An electrical device providing an interface between the mains power supply and sensitive loads (computer systems, instrumentation, etc.). The UPS supplies sinusoidal AC power free of disturbances and within strict amplitude and frequency tolerances. It is generally made up of a rectifier/charger and an inverter together with a battery for backup power in the event of a mains failure.
The UPS is plugged between the mains and the computer. Equipped with a battery bank, a voltage regulator and a fuse, it ensures high quality stabilized voltage level to the current supplying the computer. In case of unexpected failure, it prevents instant shut down of the computer and provides between 20 and 30 minutes autonomy for backup. It protects also against micro cuts (the hard drive may be harmed by failures, blackouts, cuts and voltage variations, above all during writing process). If you are connected to the ground, the UPS protects computers and networks against surges (due to lightning or technical problems).
(Uninterruptible Power Supply): A device that supplies continuous power to computers and switches by converting energy stored in batteries to 120 Volts AC. Commercial power is used to charge the batteries. In the event that commercial power is lost, a UPS will provide power until the batteries run down, commercial power is restored, or a generator is turned on. In many installations, a UPS is used for short-term outages and gives time for the generator to be started and stabilized to power equipment during prolonged power outages.
Uninterruptable Power Supply. A battery that "kicks in" when the device senses a loss of power from the primary source providing enough time to properly shut down a system or in some cases to keep the system up until power is returned. An UPS also provides protection from power surges.
Short for uninterruptible power supply, a power supply that includes a battery to maintain power in the event of a power outage. Typically, a UPS keeps a computer running for several minutes after a power outage.
Uninterrupted Power Supply. Equipment (usually a bank of batteries) that offers short-term protection against power surges and outages. Note that UPS usually only allows enough time for vital systems to be correctly powered down.
Uninterruptible Power Supply. A UPS is a device that allows your computer to keep running for at least a short time when the primary power source is lost. It also provides protection from power surges. It "kicks in" when the device senses a loss of power from the primary source. If you are using the computer when the UPS notifies you of the power loss, you have time to save any data you are working on and exit gracefully before the secondary power source (the battery) runs out. When all power runs out, any data in your computer's random access memory (RAM) is erased. When power surges occur, a UPS intercepts the surge so that it doesn't damage your computer.
Uninterruptible Power Supply. UPS keeps the server running on a battery for several minutes after a power outage, allowing for a clean shutdown without loss of data. UPS can also shield the server from line voltage spikes and drops.

Uninterruptible Power Supply A device connected between a computer and a power source that ensures that electrical flow to the computer is not interrupted because of a blackout and, in most cases, protects the computer against potentially damaging events such as power surges and brownouts.
Uninterruptible power supply. These are power supplies used in the majority of high security systems, whose purpose is to back-up the system for at least 10 minutes without mains power. The duration of this depends on the size of the UPS, usually expressed in VA, and the current consumption of the system itself.
Uninterruptible Power Source. A machine that regulates that electricity that flows into your computer. A UPS also stores a set amount of electricity, allowing you to use a computer for a short time after a brownout or blackout.
Uninterruptible Power Supply. Usually includes an inverter, drawing its power from batteries, which generates an extremely "well-behaved" AC power signal for a PBX or other equipment. The UPS cost is related to the amount of power needed and the length of time it must operate during a failure. If a particularly heavy demand is anticipated, the system can be coupled with an auxiliary generator that is started when commercial power is interrupted.

UPS systems typically provide surge suppression and may also provide voltage regulation. Small UPS systems provide battery power for a few minutes to enable you to shut down your computer.
Uninterrupted Power Supply. A power source (battery) that has surge protection. The servers are plugged into the UPS to ensure that if there is a power failure the systems keeps operating for a limited period of time in order to allow to save data in RAM and to perform a controlled shut down. Many UPSs now offer a software component that enables you to automate backup and shut down procedures in case there's a power failure while you're away from the computer. A laptop is an example of something that has a UPS function (the battery)

UPS, in computer terms, stands for Uninterruptible Power Supply. In a data centre, UPS power means that all power is fed through a battery of sorts. In the event of a power failure, the UPS will continue to feed power to the network and servers while data centre staff correct the problem or start up alternative power sources such as diesel generators. Having an Uninterruptible Power Supply in place helps to ensure maximum uptime. Open

Uninterruptible Power Supply. A device which provides back-up power in the event of failure in the primary power supply system. If there is a power-cut or drop-out the UPS will keep the system running for a finite period of time, allowing the primary power supply to be repaired and/or the system to be powered-off gracefully. This protects the equipment and the stored data.
A UPS made up of several parallel-connected UPS units with equal output ratings (P) and each equipped with its battery. If one unit fails, one or several of the others pick up the resulting excess load. If a UPS has a rated output n x P and is made up of n + k units, k is the level of redundancy for the entire set of n + k units.
