Automated 3-Phase CDN Provides Reliable High Power Consumption EUT Testing

Teseq Inc. recently released an automated 3-phase coupling/decoupling network (CDN) for EFT and surge testing.  The new CDN 3063 provides safe, reliable operation in a wide range of test setups, including higher current level and 3-phase EUT (equipment under test) testing.


The CDN 3063 comes standard with over temperature protection that allows short term operation at current exceeding the nominal rating. A phase rotation indicator in the 3-phase models shows a correctly sequenced power connection for safe EUT operation.

The new system meets IEC requirements for EUT currents over 16 A and ANSI specifications for special coupling modes and pulse amplitude control making it fully compliant with both industry standards.  For more information, please visit
