UPS / Phase Inverter Dialog Box
See the Common Schedule Dialog Box Features section for more information about how this dialog box works. This section describes the Rename, Find, Previous, Next, New, Copy, Save, and Delete buttons.
The Input KVA, Efficiency, Output KVA, Output KW, and Power Factor values are all related to each other. Use the radio buttons to choose one value from each column to calculate. The other values must be entered manually.
Input KVA: The input kVA of the UPS. If this is calculated, it is equal to Output KVA / Efficiency.
Efficiency: The efficiency of the UPS. If this is calculated, it is equal to Input KVA / Output KVA.
Output KVA: The output kVA of the UPS. If this is calculated, it is equal to Input KVA * Efficiency.
Output KW: The output of the UPS in kW. If this is calculated, it is equal to Output KVA * Power Factor.
Power Factor: The power factor of the output of the UPS. If this is calculated, it is equal to Output KVA / Output KW.
See the Distribution Equipment Dialog Box Settings section for more information about the other values and buttons in this dialog box.
