Load dump pulses have high pulse energy, which can be highly
destructive to electrical or electronic equipment. The LD N
series simulates these pulses with high energy in a range of up to
. seconds. The LD N series generates load dump pulses per
the respective requirements of the ISO -, ISO , SAE J,
SAE J and JASO standards and nearly all international manufac-
turers’ specications e.g. Ford, Chrysler, Renault, PSA, Nissan, etc.
With the built-in clipping module, the LD N series also generates
load dump pulses per international standards and manufacturer
specications.

UCS N SERIES
COMPACT SIMULATOR FOR AUTOMOTIVE TRANSIENTS
LD N SERIES
LOAD DUMP GENERATOR WITH “CLIP” FUNCTION
The ultra-compact simulator UCS N series for automotive transi-
ents combines the capabilities of EFT/burst simulators and micro-pulse
simulators as well as the necessary coupling network – up to A
depending on model – in one device. The UCS N series meets all
international standards and automobile manufacturer specications.
A wide variety of pulse form parameters can be used. The built-in cou-
pling network can be used and controlled with any device from the LD
N, VDS N, and PFS N ranges.
