will be in a power derating mode. The relationship between the output power and input voltage is illustrated in
the following illustration.
Note:
As depicted in the following illustration, the output power will derate from 100% of the rated capacity
as the input voltage drops below 304 VAC, and to 50% of the rated capacity as the input voltage falls
to 260 VAC.
5.1.6
Power Derating Based on Temperature: The Rectifier Module delivers full power when operating at an ambient
temperature of +45
°
C (+113
°
F) or below. Refer to the following illustration to view the relationship between
the output power and the ambient temperature.
Other power rating values are as follows:
•
At an ambient temperature of +50
°
C (+122°F), the power delivered by the Rectifier Module is greater
than 5400W.
•
At an ambient temperature of +55
°
C (+131
°
F), the power delivered by the Rectifier Module is greater
than 4640W.
