Determine the UPS type
According to the load requirements on output stability, switching time, and output waveform, choose the online UPS, online interactive UPS, backup UPS, sine wave UPS, and square wave UPS.
The on-line UPS has better output stability and instantaneous response ability than the other two kinds, and has better adaptability to nonlinear load. For some more sophisticated equipment, more important equipment to use online UPS. In some areas with large fluctuations in the mains, avoid using interactive and backup. To use a generator with a short UPS, use an online UPS.
Four, service ability
Each user's network characteristics and power environment are different, and the power protection requirements also change. Users may encounter different problems when using UPS. They want to purchase products and services that fully meet their actual needs and are concerned about the equipment investment cycle, long-term rate of return, and investment risks. The reality is that the vast majority of users lack personnel in this area. Therefore, excellent service system and active service have become an important factor that users must consider when purchasing UPS.
