NSG 435 ESD Simulator
Page 2
Combining ease of operation and ergonomic design with exceptionally high functionality,
the NSG 435 offers all the features of a comprehensive ESD test system in a compact,
light-weight, hand-held instrument.
ESD tests form a particularly powerful part of EMC test strategies: they are used to verify
complete systems and identify disturbances in installations, as well for type testing.
The high frequency components of the pulse help diagnose immunity failures caused by
bad cabling or system composition, and can also indicate grounding problems.
Ergonomic design and high functionality
Careful attention has been paid to ergonomic design to ensure that the NSG 435 sits easily in the
hand without being tiring or uncomfortable during long or repeated test procedures. The liquid crystal
display panel is clearly visible at all times in the working position and all the controls are conveniently
at the user’s fingertips.
The NSG 435 is powered by a rechargeable battery supply, so there is no separate high voltage
generator or stiff connecting cable to hinder access to the EUT. The battery, which lasts for several
days under normal test usage, can be easily interchanges and recharged in just three hours.
Microprocessor-based control and a five-key pad give access to the comprehensive range of built-in
functions. The liquid crystal display shows the operating status and all user-programmed test
parameters continuously. A discharge pulse counter is incorporated and a further handy feature is the
provision of a preset counter for long duration tests and remote use.
The NSG 435 has its own high voltage generator producing pulses up to 16.5kV. In addition to the
pre-programmed, standard IEC pulses, the user can create custom tests, using single or repetitive
discharges with selectable frequencies, discharge rates and manual or automatic polarity switching.
A unique feature is the detection of a real or valid discharge thereby avoiding misleading discharge
counts. This is especially important during long term and remote test set up.
● User programmable discharge voltage 200V to 16.5kV
● Built-in IEC 1000-4-2 test settings
● Battery powered
● Compact and Iightweight design
NSG 435
A new concept
The NSG 435 comes with a
150pF/330Ω discharge network
for tests to IEC 1000-4-2, and a
range of interchangeable
discharge networks is available
for other standards including
EN, ANSI-IEEE, ISO, etc.
The discharge voltage of up to
16.5kV for air discharges and
up to 9kV for contact
discharges ensures a
comfortable margin over and
above the values required for
the standard tests.
