The coupling clamp is primarily used to
inject fast transient and burst interference
pulses into signal and data cables, i.e.
into any type of connection to peripheral
equipment.
The IEC standard 61000-4-4 also allows
the capacitive coupling method to be
used for pulse injection into ac and dc
power lines when no appropriate
decoupling network is available.
The coupling capacitance (typically
100pF) between the coupling clamp and
the cable inserted depends on the cable
type, the diameter and other factors like
screening, etc.
The CDN 8014/8015 conforms to the
standard in every respect.
It has a sturdy construction is suitable for
laboratory and on-site use. The precision
manufactured German silver coupling
plates are housed in wooden case with a
crystal-clear protective lid.
Contact plates on both sides of the case
ensure the necessary grounding to the
reference plane.

CDN 8014 / CDN 8015
CDN 8015 with safety interlock facility
CDN 8015
The CDN 8015 provides an interlock
facility for safety purposes.
When used with any current Schaffner
burst generator or BEST combination test
generator, the coupling clamp interacts
with the generator preventing the output
of a high voltage pulses whilst the
protective cover is open.
