3.3.5.2 Environmental temperature
The devices BM4400, BM4600, BM4700 were designed to be operated at an environ-
mental temperature of T
Rated
= 40 °C. If the devices are operated at temperatures be-
tween 40 °C and 55 °C the permitted output current (I
O
) must be reduced according to
the following formula:
The coolant temperature complies with the environmental temperature of air-cooled de-
vices, with the water temperature of water-cooled devices and the surface temperature of
the cold plate/mounting panel of devices with cold plate cooling.
3.3.5.3 Supply voltage
Above rated 
supply voltage
The rated voltage is 3 x 400 V
When having input voltages above the rated supply voltage the output currents must ac-
cordingly be reduced at a constant output power.
