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.
