With the continuous development of modern society, people's life, production demand is constantly improving，Electricity is indispensable for us, because the power supply pressure is too large, or the current is unstable，In order to ensure constant electricity, more and more enterprises and individuals choose uninterruptible power supply, has become an indispensable equipment in our life，So the first choice of UPS power supply should be considered what problems？
There are several points to consider when choosing a UPS for the first time：
1. Stability of product
Because the UPS functions as a power supply, its own stability is more important，Therefore, when users choose UPS products, the quality of UPS products must be considered first, and the quality of products is the first requirement for users to choose products。
2. Backup time of UPS power supply
Backup time is an indicator that many users pay attention to when purchasing UPS products. When a power failure occurs, the backup power supply of the UPS plays the role of emergency power supply, providing valuable time for maintenance personnel in the equipment room to deal with unnecessary accidents。
3. Determine the UPS type
According to the load to output stability, switching time, output waveform requirements, to determine the choice of online UPS, online interactive UPS, backup UPS, sine wave and square wave type。
The output stability of the online UPS, the instantaneous response ability is stronger than the other two, and the adaptability to nonlinear loads is also stronger，For some more sophisticated equipment, the more important equipment should use online UPS，In some areas where the mains fluctuation range is relatively large, avoid the use of interactive and backup types. If you want to use a generator with a short-delay UPS, it is recommended to use an online UPS。
UPS power supply is the power guarantee of enterprise data center, which ensures the continuity and safety of power supply, and plays an important role in security protection at all times，As an important part of UPS, battery is undoubtedly the last insurance of UPS power supply，How to improve the means and level of battery monitoring and management in UPS power supply and reduce or eliminate the incidence of battery accidents is undoubtedly of high economic value to users。
A battery management system is a good solution，Real-time monitoring of the operating status of the battery, the first time to understand the actual performance data of the battery，Find hidden faults in time and issue alarms to guide maintenance personnel to deal with them correctly to avoid unnecessary accidents。
