Setup current limiter for surge current
The current limiter stops the test run when during a test the measured peak current of a surge pulse is higher
than the preselected current value. This safety function protect the EUT for further surge pulses can occur any
dangerous situation.
Depends of the different impedance of the surge generator, one current limiter for each impedance (2
, 12
) is
available.

= Current limiter Differential mode (line to line):
The generator impedance is 2

= Current limiter Common mode (line to ground):
The generator impedance is 12
REMARK
The current limits in Software and Manual operation are two individual settings.
Software
uses the
software settings
for I_D and I_C
Manual operating
uses the
device settings
for I_D and I_C
Note :
Surge pulses with the coupling position “\” (potential free output at the rear side of the generator ) use the settings of
common mode. This is general used for the coupling network CNV 504 / 508 with 42
impedance. Using a coupling
network CNI 503 or CNV 503, UCS uses the limits of differential and common mode.
