Lead timeSpecial Order - Call for Quoted Lead Times
Run time for load
Enter the total load (power draw) of all devices that will be protected by the UPS. This will be used to estimate the run time of your devices during a total power outage. Adding run time increases availability by allowing the system to operate through longer outages without shutting down.
Min-max: 12500-125000 W
Max. Capacity Used
The maximum percentage of UPS capacity used to support your specified load.
