10.4.2 General technical data, 400 V inverters
Property Version
Line voltage 3 AC 380 V … 480 V ± 10% (in operation -20% < 1 min)
Line system configurations Grounded TN/TT line systems or non-grounded IT line systems
Line impedance Uk < 4%, line reactor is not required
Power factor λ > 0.9
Output voltage 3 AC 0 V … 0.95 x input voltage (max.)
Input frequency 50 Hz … 60 Hz, ± 3 Hz
Output frequency 0 … 550 Hz, depending on the control mode
Inrush current < LO base load input current
Overvoltage category ac‐
cording to EN 61800-5-1
III for line supplies
Pulse frequency 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.
