MANUAL SURGE COUPLING NETWORK
CDN 3083-S100M
For EUT power supplies up to
620 V
100 A per phase with generous
overload capacity
Complies with IEC/EN 61000-4-5
and ANSI C62.45
Easy upgradeable from IEC to
ANSI coupling
The manual coupling network CDN 3083 fulfi ls the requirements called for in the Surge standard IEC/
EN 61000-4-5: 2005, including the new features concerning high currents as well as in the ANSI C62.45
standard and relevant standards.
The form of construction selected suits the demands placed on the instrument in its working environ-
ment. In its basic form, the coupler is made for use on a fl oor or for table top placement in an EMC
laboratory or in a development workshop. It can be even mounted onto the wall to have free space on
test bench, for instance.
High-current couplers often have to be taken to a test site when it is commonly impossible to move a
large installation into the laboratory. For more convenience, the CDN 3083 can be disassembled in handy
parts and can easily move to other places. Wheels with braking features can be mounted to manoeuvring
the coupler even on ramps and uneven surfaces.
In order to keep voltage losses within reasonable limits with increasing current levels, the IEC has defi ned
three classes of fi lter inductances, namely: up to 20 A, 20 to 60 A and 60 to 100 A. Classic high-current
couplers cannot therefore be used any longer for lower current levels since the fi ltering effect is insuf-
fi cient. Through the use of special choke technology, Teseq has managed to avoid the costly disadvantage
of using several couplers. By using an auto-adaptive back fi lter, the CDN 3083 fulfi ls the requirements for
both protection and voltage drop over the range from just a few amps to full load.
The nominal maximum current rating of 100 A per phase can, during short test periods, be consider-
ably exceeded. The unit will tolerate the frequently encountered inrush currents without complaint
and, in extreme cases, it can be overstress until the internal environment have reached the maximum
temperature.
For single phase application even 200 A per phase is possible by paralleling 2 decoupling network paths
and adding decoupling units.
The CDN 3083 is tested for safety in compliance with IEC 61010. The rugged connection terminals together
with the solid earth line assure a proper connection, this in combination with a solid housing.
Technical specifi cations
The coupling network CND 3083 serves to inject the following standardized surge pulses from the surge
generator into the mains supply to the device under test:
Voltage surge of up to 8 kV which follows the 1.2/50 µs curve (open-circuit)
Current surge of up to 4 kA which follows the 8/20 µs curve (short circuit conditions)
The CDN 3083 is designed to be used with an EUT supply of up to 620 V rms at 100 A. Operation is manual,
simple and designed to be safe. The construction takes into account the relevant specifi cations issued
by the VDE and IEC concerning personal safety. The CDN 3083 enables coupling modes with all types
of symmetrical and asymmetrical coupling given in the IEC 61000-4-5 and ANSI C62.41 2002 and other
related standards.
