Uk ≥ 1 %, for lower values, we recommend a line reactor, or a Power Module
with the next higher power rating.
Line reactor not required
Power factor λ FSA … FSC
FSD … FSF
0.7 without line reactor for Uk ≥ 1 %
0.85 with line reactor for Uk < 1 %
0.95 line reactor not required
Inrush current
< LO base load input current
Overvoltage category acc.
to EN 60664-1
The inverter insulation is designed for surge voltages according to overvoltage Category III.
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
If you increase the pulse frequency, the inverter reduces the maximum output current.
