Line voltage
3-phase 380 … 480 VAC ± 10%
Output voltage
3-phase 0 VAC … input voltage x 0.95 (max.)
Input frequency
50 Hz … 60 Hz, ± 3 Hz
Output frequency
0 Hz … 550 Hz, depending on the control mode
Power factor λ
0.7 ... 0.85
Inrush current
< LO base load input current
Overvoltage category ac-
cording to EN 60664-1
The inverter insulation is designed for surge voltages according to overvoltage Category III.
Short-circuit current rating
(SCCR)
≤ 65 kA rms
Pulse frequency (factory
setting)
• 4 kHz for devices with an LO base load power ≤ 90 kW
• 2 kHz for devices with an LO base load power > 90 kW
Can be set in 2 kHz steps in the range 2 kHz … 16 kHz.
If you increase the pulse frequency, the inverter reduces the maximum output current.
