kVA Power Estimator Table



You can build a kVA tally by listing your protected equipment into the Power Estimator Table below.
 
If you have been unable to locate manufacturer's information for any of your equipment, and measuring its consumption isn't possible, you can interpolate from the examples shown for each equipment type - workstation, server, etc..

Enter ratings for all of your equipment in the table below for your total kVA.

Sample ratings are given to help you, but we suggest these figures should only be used as a guideline.
