1)
All rated values refer to a DC link voltage of 540 V, a control voltage of 24 V and an environmental temperature of 40 °C.
2)
Using the power choke listed in ZPower chokes– from page 288 at a power supply with U
K,power supply
= 0.4 %.
3)
The output voltage is a pulsed DC voltage. The operating range refers to the RMS of the fundamental wave. 

5)
RMS at an environmental temperature of 40 °C.
6)
At rated power supply voltage the unit supplies rated / maximum output currents. With input voltages above the rated power supply
voltage the output currents must be reduced at constant output power

7)
The input current must be reduced between 40 °C and 55 °C. Refer to correction factors at changed operating conditions ZEnviron-
mental temperature– on page 55
8)
Two temperature values may occur (cooling air, which flows through the internal space of the device / cooling air, which flows through
the heatsink). Enter the higher value. 

9)
The possible overload time at this moment is dependent of the device load and the heat sink temperature. The device load is determined
by the overload monitoring of the device.
10)
The sum of the instantaneously drawn power via the DC link terminals and the input power (motor output / motor efficiency) of the motor
at the same time may not exceed the maximum power input of 250 kW and 315 kW.
11)
If UL508C is complied with: max. 4.0 A.
12)
Refer to ZMotor requirements– on page 52.
13)
If UL508C is complied with:
The permitted typical motor output is limited to 295 kW at a maximum.
The device BM5573 belongs to the category < 400 HP, < 298 kW
ratings complying with table 45.1 of UL508C. Therefore, the short-circuit test using 18k A can be executed. Baumüller does not offer
devices in the class 600 HP, 447
kW with 30 kA short-circuit current in accor
dance with UL508C.
