Permissible converter overload
The converters have different power ratings "High Overload" and "Low Overload" depending
on the expected load.
Figure 6-1
Note
Please note the base load (100 % power or current) for Low Overload is higher than the
base load for High Overload.
The load characteristics shown in the diagram are only examples. We recommend the use of
the "SIZER" engineering software to select the appropriate Power Modules using duty
cycles. See Sizer download
