What are the specific use notes?
According to IDC statistics: 45% of all computer failures are caused by power problems. In Chinese, the number of big city blackout for an average of 0.5 times per month, medium city is 2 times / month, a small city or town is 4 times per month, at least nine kinds of problems: power grid, lightning surge, and peak frequency oscillation, voltage mutation, voltage fluctuation, frequency drift, voltage sag, pulse interference therefore; from the perspective of improving the quality of the power supply to the computer is equipped with a UPS is very necessary.
In principle, the UPS is a power electronics device incorporating digital and analog circuits, automatic control inverters, and maintenance free storage devices;Functionally, UPS can effectively purify the city power when the city power is abnormal. It can also supply power to the computer and other equipment for a certain period of time when the city power breaks suddenly, so that you can have enough time to cope with it;From the use, with the coming of information society, UPS is widely used in the information collection, transmission, processing, storage and application to each link, its importance is increased with the increasing importance of information applications.
UPS is the abbreviation of uninterruptible power system, which is an important external equipment to provide continuous, stable and uninterrupted power supply.
In addition, network equipment and communication equipment precision is not allowed with intermittent power, to the server as the core network center to be equipped with UPS is self-evident, even an ordinary computer, the use of three months after the data file has exceeded the value of software and hardware, so as to prevent data loss with it is necessary for the UPS. UPS battery classification edit this paragraph UPS according to the principle of divided into backup, online and online interactive three categories.
On line UPS structure is more complex, but the performance is perfect, can solve all power problems. Such as the four PS series, its remarkable characteristic is to continue zero interrupt output pure sine wave AC power supply, can solve all the problems of the peak surge, frequency drift; due to the need for greater investment, usually in the key equipment and network center of electric power demanding environment application.
