Select all that apply, then click Submit answer.

  • ○

    The capacity algorithm for a single air conditioner with UPS is 1.2* 1.732*full load current*380*0.8/0.9
    If you configure UPS5000E, you need to configure at least one 25kVA power module
    If you configure UPS5000E, you need to configure at least two 40kVA power modules

  • ○

    The capacity algorithm for a single air conditioner with UPS is 1.2*5* 1.732*full load current*380*0.8/0.9

  • ○

    The UPS capacity requirement of a single air conditioner is 15.8kV
  • ○

    The UPS capacity requirement of a single air conditioner is 79.0kV
  • ○

    If a group of air conditioners is connected to a set of UPS systems, then it is necessary to multiply the number of air conditioners running at the same time on the basis of a single UPS, such as 5+1 cold backup configuration, then it needs to bebased on the capacity requirement of a single air conditioner UPS Multiply by 5 to get total UPS capacity requirement, configure
