Manufacturers : Power supplies : UPS power supply
A large number of electronic devices, such as cordless telephones, desktop computers, baby monitors, alarm systems, video surveillance systems, and answering machines, which are found in the home and office do not possess a backup power supply. When power supply is interrupted, these electronic devices are inoperable. An uninterruptible power supply (UPS) is a type of power supply used to power and protect an electrical load that is sensitive to fluctuations in or the absence of electrical power. An uninterruptible power supply is typically used as a buffer between commercially supplied power and an electrical load, such as a computer, that requires precise or uninterrupted power. A UPS serves to keep a computer operating by supplying power thereto when the power supply from the commercial power is stopped, for example, a power failure or breaker trip due to overload occurs. An uninterruptible power supply uses an inverter to convert a direct current (DC) from a battery into an alternating current (AC). A UPS generally receives power at an input port from a utility power source and supplies power from the input port to an output port for critical loads. When the power at the input port from the utility power source is disrupted, the UPS provides power to the output port adequate for the demand of the critical loads from a secondary power source such as a battery or capacitor. The UPS uses the commercially supplied AC power to charge a DC battery. A UPS generally comprises a rectifier, inverter, battery charger, DC battery, and other components, all housed within a single case or package. Uninterruptible power supply systems are typically classified into static UPS systems and dynamic UPS systems, static UPS systems compensate for interruptions of a AC power supply by means of electric energy stored in batteries whereas dynamic UPS systems use kinetic energy stored in a flywheel to this end.
