    en.wikipedia.org/wiki/Uninterruptible_power_supply

    A large data-center-scale UPS being installed by electricians. An uninterruptible power supply (UPS) or uninterruptible power source is a type of continual power system that provides automated backup electric power to a load when the input power source or mains power fails.

    en.wikipedia.org/wiki/APC_Smart-UPS

    The Smart-UPS is a series of enterprise-level uninterruptible power supplies (UPS) made by American Power Conversion (APC). [1] Most of the units have a SmartSlot (with the exception of SC and SMC series) which accepts an optional interface card providing features ranging from network connectivity to temperature and humidity monitoring.

  5. Diesel rotary uninterruptible power supply - Wikipedia

    en.wikipedia.org/wiki/Diesel_rotary...

    Most forms of uninterruptible power supply (UPS) can be either powered by battery or flywheel energy. These are ready for immediate use at the instant that the mains electricity fails, but the relatively small and finite amount of stored energy they contain makes them suitable for short periods of use, typically in the order of a few dozen minutes to a couple of hours depending on the actual load.

  6. Continual power system - Wikipedia

    en.wikipedia.org/wiki/Continual_power_system

    A continual power system is a system for reliably supplying uninterrupted power. Examples of a continual power system include uninterruptible power supplies and emergency power systems . The need for continual power systems has risen because more and more essential services depend on consistent power, such as lighting, computing, and ...

  7. Backup battery - Wikipedia

    en.wikipedia.org/wiki/Backup_battery

    Backup batteries are used in uninterruptible power supplies (UPS), and provide power to the computers they supply for a variable period after a power failure, usually long enough to at least allow the computer to be shut down gracefully. [4] These batteries are often large valve regulated lead-acid batteries in smaller or portable systems.

  8. 80 Plus - Wikipedia

    en.wikipedia.org/wiki/80_Plus

    Typical computer power supplies may have power factors as low as 0.5 to 0.6. [14] The higher power factor reduces the peak current draw, reducing load on the circuit or on an uninterruptible power supply. Reducing the heat output of the computer helps reduce noise, since fans do not have to spin as fast to cool the computer. Reduced heat and ...
