Derating

Temperature derating
In the temperature range +40...50 °C (+104...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):
k
Altitude derating
At altitudes from 1000 to 2000 m (3300 to 6561 ft) above sea level, the continuous output
currents given above must be derated 1% for every 100 m (328 ft). For a more accurate
derating, use the DriveSize PC tool.
