UPS is uninterruptible power supply, is to protect the computer system after a power failure to continue to work for a period of time to enable the user to emergency storage, so that the user does not affect the work of the system equipment due to power outages.UPS will be connected to the battery and the host computer, through the host computer inverter and other modular circuits will be converted from DC to utility power equipment, used to give the computer network system or other power electronics and so on, to provide a stable, Uninterrupted power supply.
UPS system equipment, when the utility power input is normal, the UPS will be the utility voltage regulator supplied to the load, at this time the UPS is an AC voltage regulator, but also to the machine battery charging; when the accidental blackout, the UPS will immediately battery power, through the inverter switching conversion method to the load to continue to supply 220V AC power to the load to maintain the normal work and protect the load software and hardware from damage. The UPS will immediately supply 220V AC power to the load through the inverter switching method to keep the load working normally and protect the load software and hardware from damage.
UPS can meet China's power grid environment and network monitoring and network systems, medical systems and other power grid reliability requirements, to overcome the centralized power supply of medium and large-scale computer network systems caused by the increasingly severe problems of the power grid environment, and the use of new digital technology development. The third generation of industrial frequency pure online intelligent UPS, the implementation of online maintenance management can avoid the shortcomings of the traditional methods to achieve good benefits.
Expanded Information:
The duration of uninterrupted power supply of UPS is limited. The time is limited by the amount of energy stored in the battery itself. When an outage occurs, then what needs to be done while the UPS battery is powered is to restore AC power, for example by enabling a backup AC circuit and making the oil generate power. If not, then you need to urgently save the disk and wait for AC power to return to normal before proceeding.
UPS is required in important and major occasion places. Institutions like banks, stock exchanges, internet, data centers, etc. need UPS power. Once the power outage, UPS can instantly start the battery power supply to maintain the load in the normal power supply of critical information equipment to ensure that the information system software and hardware without accident or data loss. Like some of the backstage of the main venue, to maintain normal power supply also need to use UPS.
UPS in the Chinese market China has its own brand. Kewa has broken through the "no master-slave adaptive multi-machine parallel control" "high-power three-phase UPS" and other industry bottlenecks in technology, and continue to introduce new high-end UPS products of various power levels, breaking the monopoly of foreign brands of high-end UPS technology in China. The products are widely used in the Bird's Nest, the main venue of the Beijing Olympic Games, the main stadium of the Women's World Cup in Shanghai, and the Three Gorges Hub Project.
