ESD Simulator System NSG 432
l Tests to standards such as IEC, ANSI-IEEE,
VDE, NAMUR,
l MIL, ISO and SAE
l Contact discharge adapter
l Mains or battery powered options
available
For very high voltage discharges, such as might be
required to meet military specifications or for special
applications, the NSG 432
ESD simulator system
from Schaffner can be used to generate electrostatic
discharges up to 25kV.
The NSG 432 is a compact, hand-held instrument,
with a range of high voltage discharge networks for
testing to various standards, including
IEC 61000-4-
2. There is also a power supply, a power supply with
preset counter, a mains independent battery pack, a
contact discharge adapter and a range of
accessories.
The high voltage discharge network appropriate to a
particular application is simply fitted on to the
lightweight, robust housing. A multi-turn
potentiometer is used to set the discharge voltage,
which is then clearly displayed on an LCD and a
toggle switch sets the operating mode to single
pulse or repetitive 20Hz pulsing. The pulse trigger is
built into the hand grip. For multiple discharge
testing, a tripod mount is available.
