UPS Battery Backup Run Time
Online uninterruptible power system UPS in the 400kVA range (typically 3-phase, double-conversion topology) offer customizable backup times through external battery cabinets. Backup duration depends on the number of batteries. It also depends on their capacity (Ah), voltage, and load. The load is assumed to be a full load of 400kW power factor for calculations. Standard configurations often provide 3-5 minutes. Extended runtimes like 15 minutes, 30 minutes, 1 hour are achieved by adding battery strings.
