10.1.6. 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 (2Ω, 12Ω) is
available.

Differential mode (line to line): The generator impedance is 2Ω
Common mode (line to ground): The generator impedance is 12Ω
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 42Ω impedance. Using a coupling network CNI 503 or
CNV 503, UCS uses the limits of differential and common mode.
