Technical data, 400 V inverters

Motors for 400 V Power Modules
For the 400 V Power Modules, induction motors are permissible in the range from
25 % ... 150 % of the inverter power without any restrictions.
Note
Motors for inverter operation
Only use motors that are suitable for operation with inverters with a DC link.

Version
3 AC 380 V ... 480 V ± 10 % (in operation -20 % < 1 min)
Grounded TN/TT line systems or non-grounded IT line systems
Uk < 4 %, line reactor is not required
> 0.9
3 AC 0 V ... 0.95 x input voltage (max.)
50 Hz ... 60 Hz, ± 3 Hz
0 ... 550 Hz, depending on the control mode
< LO base load input current
III for line supplies
Factory setting
● 4 kHz for devices with an LO base load power < 75 kW
● 2 kHz for devices with an LO base load power ≥ 75 kW
Can be adjusted in 2 kHz steps as follows:
● 2 kHz ... 16 kHz for devices with an LO base load power < 55 kW
● 2 kHz ... 8 kHz for devices with an LO base load power ≥ 55 kW
● 2 kHz ... 4 kHz for devices with an LO base load power ≥ 110 kW
If you increase the pulse frequency, the inverter reduces the maximum output current.
≤ 100 kA rms
Branch protection and short-circuit strength according to UL and IEC
