How to buy USP？

UPS, as a protective power supply equipment, its performance parameters are of great significance and should be the focus of our consideration when purchasing. The wide input range of the mains voltage indicates a strong utilization of the mains (reduce battery discharge). The output voltage and frequency range are small, it shows that the ability to adjust the mains is strong, and the output is stable. The waveform distortion rate is used to measure the stability of the output voltage waveform, and the voltage stability indicates the stability of the output voltage when the UPS is suddenly added from zero load to full load.

In addition, UPS efficiency, power factor, and conversion time are all important parameters that characterize UPS performance, which determine the protection capability of the load and the utilization rate of the utility power. The better the performance, the stronger the protection capability. In general, the offline UPS has the worst protection to the load, the online interactive type is slightly better, and the online type can solve almost all common power problems. Of course, the cost also rises with the enhancement of performance. Therefore, when purchasing UPS, users should choose different types of UPS according to the degree of power requirements of the load and the importance of the load.
