The new, modular CDN 3061 is an easily upgradeable test instruments that maximize the user’s initial investment. Users can select a CDN configuration that fulfills their basic testing needs with the assurance that they can upgrade it to a version to fit different generator compatibility as their testing requirements change. The CDN 3061 is 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 automated single-phase coupling network incorporates surge and burst coupling for continuous EUT currents of up to 16 A and complies to the requirements for the surge standard IEC/EN 61000-4-5:2005, as well the coupling modes given in the ANSI C62.45 standard and for burst standard IEC/EN 61000-4-4:2005. This network features a module for the power quality test required by IEC/EN 61000-4-11 and IEC/EN 61000-4-29. Automated variac accessories are available for connection to the CDN to perform the variation test described in IEC/EN 61000-4-11. Voltage variation test parameters are set via the generator’s user interface.
