Why is UPS measured in kVA?
UPS systems are often “sized” by a kW (kilowatts) and/or a kVA (kilo-volt-amperes) rating. For example, a 1 kVA UPS means its circuitry can handle 1,000 volt-amperes. In physics, the basic rule for AC power states “watts = volts x amps.” So a 1,000VA UPS should be able to handle 1,000 watts, right?

How do I calculate UPS size needed?
How to size a UPS
- List all equipment to be protected by the UPS.
- List the amps and volts for each device.
- Multiply the VA by the number of pieces of equipment to get the VA subtotals.
- Add the VA subtotals together.
- Multiply the total by 1.2 to get the grand total.
- Use the grand total to select a UPS.
