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 supply voltages above the rated supply voltage, the output current is to be reduced at
constant output power, accordingly.
