106 Technical data
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
):
Altitude derating
At altitudes 0 … 1000 m (3300 ft), no derating. At altitudes from 1000 to 4000 m (3300 to
13123 ft) above sea level, the continuous output currents given above must be derated 1%
for every 100 m (328 ft).
