Figure 19: Derating of Output Current Based on Altitude at T
AMB, MAX
6.6.4 Derating for Ambient Temperature and Switching Frequency
 NOTICE
FACTORY DERATING
Danfoss drives are already derated for operational temperature (55 °C (131 °F) T
AMB, MAX
and 50 °C (122 °F) T
AMB, AVG
).
Use the graphs in the following table to determine if the output current must be derated based on switching frequency and ambient
temperature. When referring to the graphs, I
out
indicates the percentage of rated output current, and f
sw
indicates the switching
frequency.
