Furthermore, there is a limited (and uncommon) range of AC INPUT voltage between 132 Vrms
and 160 Vrms in which the total output power that can be derived from the AC INPUT is also
derated, as shown in the graph below.

Note that the full rated output power of 1250 W can be derived from the AC INPUT having a voltage
within this uncommon range for 15 seconds before the UPS will switch over to the DC INPUT or the
BATTERY PACK. Also note that the UPS can drive it full rated power for a 2 second interval even if the AC
INPUT voltage drops below 90
Vrms
