Coupling/decoupling network

  • 22-Feb-2010 09:37 EST

Teseq designs an automated three-phase coupling/decoupling network (CDN) for electrical fast transient (EFT) and surge testing. According to the company, the CDN 3063 provides safe, reliable operation in a wide range of test setups including higher current level and three-phase equipment under test (EUT) testing. To prevent damage to internal components, 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 three-phase models shows a correctly sequenced power connection for safe EUT operation. Available in a burst-only configuration (CDN 3063-B32), with surge function only (CDN 3063-S32), or in a combined model (CDN 3063-C32) that provides both, the modular CDN 3063 is easily upgraded to protect a user’s initial investment and quickly adapts to changing test environments. The system meets IEC requirements for EUT currents over 16 A and ANSI specifications for special coupling modes and pulse amplitude control.
