WebOct 4, 2024 · How is UPS kVA rating calculated? UPS systems are often “sized” by a kW (kilowatts) and/or a kVA (kilo-volt-amperes) rating. This means that the formula for watts = volts x amps x power factor. For example, 1kVA UPS from N1C has the capacity to power 900 watts of connected equipment. This means the UPS has a “power factor” of 0.9.
