In the temperature range +35…50 °C (+95…122 °F), the rated output current is derated
by 1% for every added 1 °C (1.8 °F). The output current can be calculated by multiplying
the current given in the rating table by the derating factor (
k ):

Altitude derating
At altitudes from 1000 to 2000 m (3300 to 6561 ft) above sea level, the derating is 1%
for every 100 m (328 ft). Multiply the output current given in
Ratings (page 197) by the
coefficient value given in this table.
