Regardless of what UPS you use, you will have less than 10 minutes to shut down equipment should your power fail. The power that a UPS is able to produce depends on it’s VA rating. This alone, however, will not determine how much power you will get out of the unit. Rather, how much equipment you have connected to it will give you a good indication. This is known as the ‘load’. As an example, one computer, running a single monitor would have a load of less than 300 VA yet requires a unit of 650VA to have enough time to close your work down and turn the computer off safely should power fail.

This means that the amount of equipment that you need to run, and the power that equipment draws, determines the size of the UPS you will need. Power Shield has a full range of UPS products to meet different requirements ranging from 650 to 100,000 VA and we can help you determine what product will best suit your needs. For those with specific requirements, we also have an online tool that can help you determine the best Power Shield UPS for you.
