• 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 1250 W up to an ambient temperature of 50
o
C (122
o
F) and then derate to 1125 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.

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 MPC will switch over to the DC INPUT. Also note
that the MPC can drive it full rated power for a 2 second interval even if the AC INPUT voltage drops
below 90 Vrms.
