Figure 2 indicates the total steady-state output power that the UPS can draw from the AC INPUT
vs line voltage. See Figure 3 for information on transient conditions.

UPS Output Power vs. 3-Phase AC Input Voltage
Steady State
Figure 2
• If the AC INPUT voltage is above 100V
L-vN
, then the UPS can deliver its full rated output power
of 1250 W from the AC INPUT for an ambient temperature as high as 55
°
C (131
°
F) without
needing to switch over to the optional DC INPUT or the internal BATTERY PACK
• If the AC INPUT is between 100V
L-vN
and 85V
L-vN
then the total output power that can be
derived from the AC INPUT linearly decreases from 1250 W at 100V
L-vN
to 1000 W at 85V
L-vN
.
For example, the total output power that could be drawn from the AC INPUT would be 1083
W at 90V
L-vN
. If the total output power is greater than this derated value, the UPS will switch
to the DC INPUT (if it is available and >22 V) or the internal BATTERY PACK.
