Teseq CDN 3063

Description

The new, modular CDN 3063 continue Teseq’s philosophy of designing easily upgradeable test instruments that maximize the user’s initial investment. Users can select a CDN from this series that fulfi ls their basic testing needs with the assurance that they can upgrade it to a model to fi t different generator compatibility as their testing requirements change. The 3063 are 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.

Phase rotation indicator in 3-phase units indicates a correctly sequenced power connection, preventing misleading line coupling, incorrect phase coupling especially precarious in synchronous mode and possible damage to the EUT.

 The fully automated IEC and ANSI compliant coupling networks fulfi ll the new requirements for EUT currents over 16 A in the surge standard IEC / EN 61000-4-5:2005, as well special coupling modes and pulse amplitude control in the ANSI C62.45 standard, the ring wave pulse given in IEC / EN 61000-4- 12:2006 and the EFT in IEC / EN 61000-4-4 Ed. 2:2004.

The CDN 3063 couples surge and burst pulses into 1-, 2- or 3-phase power mains of up to 480 V with a current range up to 32 A, 63 A or 100 A. This range incorporates the new IEC draft standard’s provision for testing EUT’s with high power consumption. Reduced decoupling inductances in series with the EUT power connection are specified in order to minimize series voltage losses. The draft standard defines three classes of filter inductance for the following current ranges: up to 16 A, 16 to 32 A, 32 to 63 A and 63 to 125 A.

 The CDN 3063 in combination with the NSG 3060 completely fulfills the unique coupling requirements specified by ANSI C62.41. This standard requires a constant peak voltage amplitude for any EUT mains voltage and phase angle. This can only be realized when the instantaneous EUT mains power voltage at the selected phase angle is taken into account when the surge voltage is applied. The instantaneous mains voltage must either be subtracted from or added to the surge generator setting in order to keep the peak level constant with respect to ground (PE). Otherwise, the mains voltage is summed with the surge pulse amplitude thereby increasing or decreasing the stress on the EUT from the desired level.

The CDN 3063 utilizes the latest electronic component technology to accomplish the unique ANSI C62.41 coupling methodology, used to measure and track the mains voltage and simultaneously control the pulse phase angle. This remarkable phase coupling accuracy can also be used for IEC coupling and exceeds the existing standard’s requirements, and represents a significant step forward in higher test results reproducibility. The CDN 3063 in combination with the NSG 3040 broadens the effectiveness of the generator extremely and complete the generator usability for a higher current level or 3-phase EUT application
