Tricky question that is as it depends on the following …
1. List all the equipment and devices you want the UPS to protect.
2. List the amps and volts for each device. These ratings can typically be found on the label on the back
of the equipment.
3. Multiply amps by volts to determine VoltAmps (VA). Some devices may list their power requirements in watts. To convert watts to VA, divide the watts by power factor.
4. Multiply the VA by the number of pieces of equipment to get the VA subtotals.
5. Add the VA subtotals together to get the total power requirement.
Then you have to determine how long you want all the kit to last on the UPS battery to determine the capacity of the UPS ‘backup time’.
