UPS Sizing : 

Follow the steps below to determine the total of the equipment loads and to confirm the proper UPS size for your application. 

• Determine the load ratings of the equipment to be protected by the UPS unit. This information should be found on the equipment’s nameplate or in the instruction manual and should be rated in either watts (W), amperes (A) or volt-amperes (VA). 

A.) If the ratings are given in watts ( W ) , multiply by 1.4 to obtain the volt-amperes (VA) requirement. This multiplier is typical of computing equipment to convert watts (W) into volt-amperes (VA). 

B.) If the ratings are given in amperes (A) , multiply by 120 (input voltage rating) to obtain the volt-amperes (VA) requirement. 

• To obtain the load requirements to be protected by the UPS, simply add all the volt-amperes
