Line voltage FSA … FSC 380 V … 480 V 3 AC ± 10%
FSD … FSG 380 V … 480 V 3 AC ± 10% (in operation -20% < 1 min)
Line supply configurations
Grounded TN/TT line supplies or non-grounded IT line supplies
Permissible line supplies (Page 46)
Line impedance FSA … FSC 1% ≤ Uk < 4%, for values smaller than 1%, we recommend a line reactor, or
a Power Module with the next higher power rating.
FSD … FSG
No restrictions
Power factor λ FSA … FSC
FSD … FSG
0.7 without line reactor for Uk ≥ 1%
0.85 with line reactor for Uk < 1%
> 0.9
Output voltage 0 V 3 AC … 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 < 110 kW
• 2 kHz for devices with an LO base load power ≥ 110 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 output of 55 kW … 250 kW
If you increase the pulse frequency, the converter reduces the maximum output current.
Current reduction as a function of the pulse frequency (Page 98)
Short-circuit current
(SCCR) and branch protec-
tion
Maximum permissible line short-circuit current ≤ 100 kA rms
Branch protection and short-circuit strength according to UL and IEC
