Total load supported by the parallel POD for each of these configurations is 20kVA. If two UPSs are connected to | ||||||||||||||||
the parallel POD, each provides 10kVA. If three UPSs are connected to the parallel POD, each provides 6.67kVA. | ||||||||||||||||
This example is the full load capacity of the parallel POD. |
