Power Derating Based on Voltage [R48-2000e (1R482000e)]
• Power Derating Based on Temperature: The rectifier delivers full power when operating at an ambient
temperature of +45°C (+113°F) or below (1R482000 and 1R2000H) or +55°C (+131°F) or below
(1R482000e). Each rectifier continuously monitors the ambient temperature surrounding the power
conversion circuit. If this temperature for any reason (such as a high ambient temperature or failed fan)
increases above approximately +45°C (+113°F) (R48-2000 and R48-2000H) or +55°C (+131°F) (R48-
2000e), 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
+45°C (+113°F) (R48-2000 and R48-2000H) or +55°C (+131°F) (R48-2000e) and +80°C (+176°F) will
result in output power being decreased. Full power capability is restored when the temperature
decreases to below approximately +45°C (+113°F) (R48-2000 and R48-2000H) or +55°C (+131°F) (R48-
2000e). Refer to Figure 5 and Figure 6 to view the relationship between the output power and the
ambient temperature.
Other power rating values are as follows:
a) 1R482000 and 1R2000H:
1. At an ambient temperature of +65°C (+149°F), the power delivered by the rectifier is 1600W.
2. At an ambient temperature of +75°C (+158°F), the power delivered by the rectifier is 800W.
