Power Derating Based on Input Voltage: The rectifier power varies with changes in input voltage and output voltage. It uses
an advanced power limitation method. The lower input threshold is 85 VAC. The rectifier can provide its maximum rated
power (1000 W) as long as the input voltage is within the range of 176 VAC to 300 VAC. 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 1.2 .
Figure 1.2 Power Derating Based on Input Voltage
NOTE!
Blue Line: Linear derating from 85 VAC to 176 VAC;
Green Line:
Keeping constant power from 90 VAC to 132 VAC, the output power is 500W.
•
Power Derating Based on Temperature: The rectifier delivers full power when operating at an ambient temperature of +45 °C
(+113 °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 approxi45 °C (+113 °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 b45 °C (+113 °C) and +75 °C (+167 °F) will result in output
power being decreased. Full power capability is restored when the temperature decreases to below approxi45 °C
(+113 °F). Refer to
Figure 1.3 to view the relationship between the output power and the ambient temperature.
Other power rating values are as follows (refer to Figure 1.3 ):
a) At an ambient temperature of +55 °C (+131 °F), the power delivered by the rectifier is 1000 W.
b) At an ambient temperature of +65 °C (+149 °F), the power delivered by the rectifier is 825 W.
c) At an ambient temperature of +70 °C (+158 °F), the power delivered by the rectifier is 720 W.
Additional conditions:
When operating in ambient between 65C to 70C the rectifier can provide 825W of power if the AC input voltage is 200VAC to
250VAC and the DC output voltage setting of the rectifier module is 52VDC to 58VVDC. When operating in an ambient between 65C
to 70C the rectifier module will linearly derate to 800W if the AC input is 200VAC to 250Vac and the DC output voltage setting of the
rectifier module is 50VDC to 56VDC.
