5. Power Derating Based on Temperature: The rectifier delivers full power when operating at an
ambient temperature of +50 °C (+122 °F) or below. The 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 approxi50 °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 b50 °C (+122 °F) and
+75 °C (+167 °F) will result in output power being decreased. Full power capability is restored when
the temperature decreases to below approxi50 °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 b50 °C (+122 °F) and +75 °C (+167 °F) will result in output
power decrease. Operation above +75 °C (+167 °F) is considered abnormal and should be
used on a temporary
1
basis only.
6. 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.)
Other power rating values are as follows (refer to Figure 3):
a) At an ambient temperature of +65 °C (+149 °F), the power delivered by the rectifier is 800 W.
b) At an ambient temperature of +75 °C (+167 °F), the power delivered by the rectifier is 0 W.
NOTE! If used outdoors under full solar radiation, all the operation temperature ratings are
decreased by 15 °C.

7. Regulation :
a) Static: Steady state regulation is ±0.6 % as controlled within the rectifier for any and all
combinations of load from no load to full load, input voltage, and input frequency at a constant
ambient temperature.
b) Dynamic: Response time ≤200 us and overshot ≤5 % for load changes at 50 % - 25 % - 50 %
and 50 % - 75 % - 50 % at rated output current.
