threshold is 85 VAC. The rectifier can provide its maximum rated power (3000W) as long as
the input voltage is within the range of 176 to 305VAC. Below 176 VAC, and down to 85 VAC,
the rectifier will continue to operate normally but will be in a power derating mode. The
relationship between the output power and input voltage is illustrated in Figure 2.
Figure 2: Power Derating Based on Input Voltage
• Power Derating Based on Temperature: The rectifier delivers full power when operating at
an ambient temperature of +50°C (+122°F) or below. Each rectifier continuously monitors
the ambient temperature surrounding the power conversion circuit. If this temperature for
any reason (such as a high ambient temperature) increases above approximately +50°C
(+122°F), the rectifier will not shut down. Rather, the rectifier limits its maximum output
power to maintain the temperature of the power conversion circuit within design
parameters. Operation between +50°C (+122°F) and +70°C (+158°F) will result in output
power being decreased. Full power capability is restored when the temperature decreases
to below approximately +50°C (+122°F). Refer to Figure 3 to view the relationship between
the output power and the ambient temperature.
WARNING! The module is rated for continuous operation at full output power up to +50°C
(+122°F). Operation between +50°C (+122°F) and +70°C (+158°F) will result in output power
decrease. Operation above +70°C (+158°F) is considered abnormal and should be used on a
temporary
1
basis only.
Temporary Operation at Abnormal Temperature: Temporary operation is defined as a period of
not more than eight consecutive hours per day, and a total of not more than 15 days in a year.
(This refers to a total of 120 hours in any given year, but no more than 15 occurrences in that one-
year period.)
