1) Each range of the higher voltage classes
of the same device power can also be
selected as current range.
2) Level and duration of the peak power,
see diagram on page 31
3) The setting range extends max. to the
possible peak power.
4) Rise and fall times are defined of 10
% ... 90 % and 90 % ... 10 % of the
maximum current. (current mode
FAST, tolerance ±20 %)
5) SB4: 4 mm safety socket
BM8: M8 screw fitting
FK25: Flat copper rail 25x10 mm with
4 mm hole and M10 and M12 bolt
