• If the AC INPUT voltage is 90 Vrms AND the ambient air temperature is above 45
o
C (113
o
F),
the total output power that can be derived from the AC INPUT linearly decreases from 2500
W at 45
o
C (113
o
F) to 2000 W at 55
o
C (131
o
F). For example, the total output power that could
be derived from the AC INPUT would be 2250 W at an AC INPUT voltage of 90 Vrms and an
ambient temperature of 50
o
C (122
o
F). A higher output power than this would cause the UPS
to switch over to its DC INPUT or the internal BATTERY PACK.
• When the AC INPUT voltage is between 105 Vrms and 90 Vrms AND the ambient temperature
is between 45
o
C and 55
o
C, the total output power that can be derived from the AC INPUT
can be calculated by linearly interpolating between the curves shown. For example, the total
output power that can be derived from the AC INPUT when the voltage is 97.5 Vrms would
be 2500 W up to an ambient temperature of 50
o
C (122
o
F) and then derate to 2250 W at 55
o
C
(131
o
F).
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.

Figure 3: UPS Output Power vs. AC Input Voltage, without switching over to the DC input or battery.
Note that the full rated output power of 2500 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 the UPS can drive full rated power for a 2 second interval even
if the AC INPUT voltage drops below 90 Vrms.
