Sizing tool
UPS kVA calculator
Convert critical load to indicative UPS capacity, redundancy, and battery energy.
Indicative sizing
- Design load: 48 kW
- Recommended UPS: 60 kVA
- Modular frames (100 kVA class): 2
- Approx. battery energy: 12 kWh @ 15 min
Engineering estimate only — site power quality, crest factor, and generator sizing require a site survey.
