How to choose uninterruptible power supply？
With the continuous development of modern society, people's life and production demand is increasing, "electricity" is an indispensable thing for people, because the power supply pressure is too high, or the current is unstable, in order to ensure uninterrupted power supply, more and more enterprises and individuals have chosen uninterruptible power supply, which has become indispensable equipment in our work and life, so what problems should be considered in choosing UPS power supply for the first time?
1. Stability
Because UPS plays the role of power guarantee, so its own stability is more important, so when users choose UPS products, they must first consider the quality of UPS products, product quality is the first principle for users to choose products, through the quality can decide which brand of products they will choose.
2. Backup time
Backup time is an indicator that many users will pay more attention to when they buy UPS products. From an academic point of view, UPS is to continue to supply power to users after a power outage, which is only one of its functions, and the second function is to ensure that users can have a pure power supply.
3. Type of UPS
According to the load to output stability, switching time, output waveform requirements to determine the selection of on-line, online interactive, backup, as well as sine wave and square wave and other types of UPS.
The output stability and instantaneous response ability of on-line UPS is stronger than the other two, and it is also stronger to adapt to nonlinear load. For some more sophisticated equipment, the more important equipment should use on-line UPS. In some areas where the fluctuation range of municipal power is relatively large, avoid using interactive and backup type. If you want to use generator with short delay UPS, online UPS is recommended.
