Line supply characteristics
Three phase AC 400 V converters
Single phase AC 230 V converters
Voltage range 380 V AC to 480 V AC
1)
(tolerance: -15% to +10%)
47 Hz to 63 Hz
Current derating at high input voltages:
: For the current derating at 480 V at the
default 4 kHz switching frequency and 40 °C
surrounding air temperature, refer to the table
in Section "Converter variants (Page 19)".
200 V AC to 240 V AC
1)
(tolerance: -15% to +10%)
47 Hz to 63 Hz
Current derating at high input voltages:
Permissible supply
configuration
TN, TT, IT: FSA to FSE (unfiltered); FSE (fil-
tered)
2)
TN, TT with grounded neutral: FSA to FSE
TN, TT: FSAA to FSC (unfiltered); FSAD (fil-
tered)
TN, TT with grounded neutral: FSAA to FSC
IT: FSAA to FSAD (unfiltered)
Second environment (industrial power network)
First environment (residential power network)
Inrush current < maximum rated input current
V20 can withstand 100,000 power cycles with an interval of 30 s.
Short-circuit current
(SCCR or Icc) and
branch protection
Maximum permissible short-circuit current: 100 kA (When using fuses)
Minimum required short-circuit current: 5 kA
You can find the data for further overcurrent protection devices on the Internet:
Branch protection and short-circuit strength according to UL and IEC
(https://support.industry.siemens.com/cs/ww/en/ps/13208/man)
When the input voltage is below the rated value, current deratings are permissible and therefore the voltage-dependent
speed and/or torque may be reduced.
2)
To operate FSE (filtered) on IT power supply, make sure you remove the screw for the EMC filter.
