The new, modular CDN 3063 continue Teseq’s philosophy of designing easily upgradeable test instru-
ments that maximize the user s initial investment. Users can select a CDN from this series that ful lls
their basic testing needs with the assurance that they can upgrade it to a model to t different generator
compatibility as their testing requirements change. The 3063 are designed for maximum reliability in a
wide range of test setups. Over temperature protection, which allows short term operation at currents
exceeding the nominal rating, prevents damage to internal components. The phase rotation indicator
in 3-phase units indicates a correctly sequenced power connection, preventing possible damage to
the EUT.
These fully automated IEC and ANSI compliant coupling networks ful ll the new requirements for
EUT currents over 16 A in the surge standard IEC/EN 61000-4-5:2005, as well special coupling modes and
pulse amplitude control in the ANSI C62.45 standard, the ring wave pulse given in IEC/EN 61000-4-12:2006
and the EFT in IEC/EN 61000-4-4 Ed. 2:2004.
The CDN 3063 couples surge and burst pulses into 1-, 2- or 3-phase power mains of up to 480 V with a
current range up to 32 A. This range incorporate the new IEC draft standard’s provision for testing EUT’s
with high power consumption. Reduced decoupling inductances in series with the EUT power connection
are speci ed in order to minimize series voltage losses. The draft standard de nes three classes of lter
inductance for the following current ranges: up to 20 A, 20 to 60 A and 60 to 100 A.
The CDN 3063 in combination with the NSG 3060 completely ful lls the unique coupling
requirements speci ed by ANSI C62.41. This standard requires a constant peak voltage amplitude
for any EUT mains voltage and phase angle. This can only be realized when the instantaneous EUT mains
power voltage at the selected phase angle is taken into account when the surge voltage is applied. The
instantaneous mains voltage must either be subtracted from or added to the surge generator setting
in order to keep the peak level constant with respect to ground (PE). Otherwise, the mains voltage is
summed with the surge pulse amplitude thereby increasing or decreasing the stress on the EUT from
the desired level.
To accomplish the unique ANSI C62.41 coupling methodology, the CDN 3063 utilizes the latest electronic
component technology to measure and track the mains voltage and simultaneously control the pulse
phase angle. This remarkable phase coupling accuracy can also be used for IEC coupling and exceeds
the existing standard s requirements, and represents a signi cant step forward in higher test results
reproducibility.
The CDN 3063 in combination with the NSG 3040 broaden the effectiveness of the generator extremely
and complete the generator usability for higher current level or 3-phase EUT application.
