UNIT DATA OF THe 400V UNITS
The following characteristics indicate the permissible maximum current for the output
frequency values 0 Hz, 3 Hz, 6 Hz, 10 Hz 25 Hz and 50 Hz. If the switching frequencies
are different, there is an interpolation between the characteristics. Unit size 19 is repre-
sented exemplary.
