3.3.5.2 Environmental temperature
The
BM5500, BM5600, BM5700
were designed to be operated at an environmental tem-
perature of T
Rated
= 40 °C. If the devices are operated at temperatures between 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 and with the water temperature of water-cooled devices.
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.

Output current in dependence of the power supply voltage
Below
rated supply
voltage
The rated voltage is 3 x 400 V
The output power of the device reduces with lower power supply voltages.
