3.3.6.2 Environmental temperature
The devices BM3200, BM3300 are provided for an environment temperature of
T
rated
= 40 °C. At usage in environments with a deviating temperature between 40 °C and
55 °C the permitted output current (I
O
) is to be calculated according to the following for-
mula:
The coolant temperature corresponds to the environmental temperature.
3.3.6.3 Supply voltage
3-phase operation
above rated
supply voltage
The rated voltage is 3 x 400 V
At supp
ly voltages above the rated supply voltage, the output current is to be reduced at
constant output power, accordingly.

NOTE!
It is no derating necessary while single phase operation of a three phase device
BM3201-XT, BM3301X-XT.
