Ambient temperature derating
Ambient temperature derating
In the temperature range +45...55 °C (+113...131 °F), the rated output current is derated
In the temperature range +45...55 °C (+113...131 °F), the rated output current is derated
by 0.5 percentage points for every added 1 °C (1.8 °F). The output current can be
by 0.5 percentage points for every added 1 °C (1.8 °F). The output current can be calculated
calculated by multiplying the current given in the rating table by the derating factor (k):

Altitude derating
At altitudes from 1000 to 4000 m (3281 to 13123 ft) above sea level, the output current
derating is 1 percentage point for every added 100 m (328 ft). For example, the derating
factor for 1500 m (4921 ft) is 0.95.
For a more accurate derating, use the DriveSize PC tool.
