UPS concept and role? (The more the better) Thank you
As well as UPS efficiency, power factor, conversion time and so are important parameters that characterize UPS performance, determines the protection of the load and the utilization of electricity. The better the performance, the stronger the protection, in general, the backup UPS on the load protection of the worst, online interactive slightly superior, on-line type can almost solve all the common power problems. Of course, the cost increases with the performance of the increase. Therefore, users in the purchase of UPS, the load should be based on the degree of power requirements and the importance of different load, and select different types of UPS.
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. From the function, the 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. 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. According to the working principle is divided into backup, online and online interactive three categories. UPS as a protective power supply, its performance parameters of great significance, should be the focus of our purchase considerations. The mains voltage input range is wide, indicating that the use of electricity is strong (to reduce the battery discharge). Output voltage, frequency range is small, it shows that the mains adjustment capacity, output stability. The waveform distortion rate is used to measure the stability of the output voltage waveform, while the voltage stability is the stability of the output voltage when the UPS power supply is suddenly loaded from zero load to full load.
UPS is an uninterruptible power system (English), is able to provide a sustained, stable, uninterrupted power supply of important external equipment. UPS is a kind of energy storage device, inverter as the main component of the constant voltage constant frequency uninterruptible power supply. Mainly for a single computer, computer network systems or other power electronic equipment to provide uninterrupted power supply. When the mains input is normal, the UPS power supply will be powered to the load after the use of electricity, then the UPS is an AC mains regulator, and it also charge to the battery; when the electricity interruption (accident power failure ), The UPS power supply battery power immediately through the inverter to the load to continue to supply 220V AC, so that the load to maintain normal work and protect the load, the hardware is not damaged.
