ElectricalOM is capable of modelling multiple UPS components working in parallel. In order to model such a scheme, the user needs to follow the steps below:


  • Right click on the UPS which will be run in parallel with the new UPS and select Install supply from... option.



  • Select the same source as the selected UPS and click OK.



  • Select Parallel source operation... option from the Functions Menu.



  • Select the selected UPS from the list and click OK.



  • Now, both switches will act together and the UPS will be indicated as 2x prefix. This means there are two units of the same UPS connected to the SB1.



  • In order to add more UPS, the same procedure must be followed.
