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 and other types.
The output stability of the online UPS, the instantaneous response ability is stronger than the other two, and the adaptability to the nonlinear load is also strong. For some more sophisticated equipment, the more important equipment should use the online UPS; In areas with large mains power fluctuation range, avoid the use of interactive and backup type.
