11.7 Estimated Runtime on Internal Batteries – 50kVA
Below are charts of the estimated runtime for the 4400 Series 50kVA on internal batteries at various loads at a 0.9 and 0.8 Power Factor.
The 80-100kVA UPS is not available with internal batteries. An external battery cabinet (or equivalent) is required to provide backup power.
These runtimes are estimates based on new batteries operating at 76 °F. Actual runtimes may vary due to manufacturing variations, previous discharge
profiles, battery age, and operating temperature.
