2. What sort of sort by?
UPS according to the working principle is divided into backup, online and online interactive three categories:
Backup UPS is our most commonly used, it has an automatic voltage regulator, power protection and other UPS is the most important and most important function, although there are generally about 10ms conversion time, inverter output AC is a square wave rather than sine wave , But because of the simple structure and has the advantages of cheap, high reliability, so widely used in computers, peripherals, POS machines and other fields;
On-line UPS structure is more complex, but the performance is perfect, can solve all power problems, its salient feature is able to continue to zero interrupt output pure sine wave AC, to solve the spike, surge, frequency drift and all the power problems; Large investment, usually used in critical equipment and network centers such as power demanding environment;
[4] Modular UPS compared with the traditional UPS has many advantages, on behalf of one of the direction of development of UPS, but there are still high costs, some products, the actual reliability is not as high as the theoretical calculation, but the safety factor has been far more than Traditional UPS; the study of modular UPS will help to improve the modularity of the reliability, thereby enhancing the modular UPS in the customer's recognition, speed up the development of modular UPS. EAST (Easy) Modular UPS Each module is a stand-alone UPS, power range is complete, high efficiency and low interference, environmental protection and energy saving, high safety factor.
What is it?
UPS is an uninterruptible power supply (Uninterruptible Power Supply) in English abbreviation, is able to provide a sustained, stable, uninterrupted power supply of important external equipment.
In principle, UPS is a set of digital and analog circuits, automatic control inverter and maintenance-free storage devices in one of the power electronic equipment;
Functionally speaking, UPS can be abnormal in the mains, the effective purification of electricity; can also be a sudden interruption in the city power for a certain period of time to the computer and other equipment power supply, so you can have plenty of time to cope with;
From the use of information society, UPS is widely used in information collection, transmission, processing, storage to the application of all aspects, the importance of information applications with the increasing importance of increasing.
3. Why are you equipped with UPS?
According to IDC statistics, 45% of all computer failures are caused by the power problem; in China, the average number of major city power outages 0.5 times / month, medium city for 2 times / month, small cities or villages and towns for 4 times / month, There are at least nine problems with the power grid: power off, lightning spikes, surges, frequency oscillations, voltage ripple, voltage ripple, frequency drift, voltage drop, impulse interference; therefore, from the point of view of improving power quality, Very necessary.
In addition, the sophisticated network equipment and communication equipment is not allowed to intermittent power to the server as the core of the network center to be equipped with UPS is self-evident, even a regular computer, the use of three months after the data file And other software value has exceeded the hardware value, so to prevent data loss is also equipped with UPS is also very necessary.
