New 100 A, 3-phase Burst Pulse CDN for EFT Testing

14 August 2013 - Teseq, a developer and provider of instrumentation and systems for EMC emission and immunity testing, now offers a 100 A, 3-phase burst pulse coupling/decoupling network (CDN) designed for electrical fast transient (EFT) or burst testing. The new manual CDN 3083-B100 is ideal for use in the power and telecom industries.

This CDN can easily carry out applications that require higher AC and DC voltages as well as high inrush or pulse-shaped peak currents like those found in renewable energy. Some applications include smart grid, inverters, solar, energy monitoring as well as applications for electric vehicles and charging stations.

The CDN 3083-B100 can couple up to 8.8 kV (5/50 ns – 50 Ohms) EFT pulses simultaneously into the supply lines of the equipment under test (EUT). It is designed to be used with an EUT supply up to 690 VAC, either line-to-line or line to protective earth, or up to 1,000 VDC line-to-line or line to protective earth.

This compact, lightweight CDN is compliant to IEC 61000-4-4-Ed. 3.0. It is compatible with all brands of burst generators and is extremely portable. Teseq’s CDN 3083-B100 is convenient for field testing and allows for more set-up options in standard compliance applications because it is external to the generator and its very compact size.

Although it is designed for continuous performance up to 100 A per phase, the CDN 3083-B100 can withstand higher currents for shorter durations of time. The CDN also features built-in temperature monitoring to prevent damage to its internal components and avoid overload.

Teseq’s CDN 3083-B100 includes screw terminals rated for 200 A, a SHV burst input connector with maximum burst voltage of 8.8 kV and earth terminal grounding.

Weighing approximately 5 kg (11 lbs), the CDN is 410 mm (16.14”) wide, 170 mm (6.69”) high and 190 mm (7.48”) deep.
