Teseq offers three-phase burst pulse CDN for EFT testing

Teseq has developed a 200A three-phase burst pulse coupling/decoupling network (CDN) for electrical fast transient (EFT) and burst testing.

The CDN 3083-B200 is said to easily handle high in-rush currents and pulse-shaped peak currents, making it ideal for testing high current and high power equipment in large machines, appliances and smart grid applications.

The CDN injects fast burst pulses, up to 8kV (5/50ns – 50Ω), into the supply lines of the equipment under test (EUT).

It is designed to be used with an EUT supply up to 690VAC, either line-to-line or line-to-ground, or up to 1000VDC, line-to-line or line-to-ground.

Compliant with IEC 61000-4-4, the CDN 3083-B200 is compatible with all brands of burst generators. The system is said to be compact, lightweight and easy to handle.

It is especially convenient for off-site testing as well as allowing for more set-up options in standard compliance applications, where the distance between the CDN and EUT is short and the use of combined CDNs cannot meet the requirements set by testing standards.

To prevent damage to internal components, the network features a large overstress capability and a built-in thermometer that monitors temperature to avoid overloa d. Although designed for continuous performance up to 200A per phase, the CDN can withstand considerably higher currents for shorter durations. The network features screw terminals rated for 200 A, a maximum burst voltage of 8,000 V and earth terminal grounding, and weighs approximately 11kg and is 430mm wide, 310 mm high and 190 mm deep.
