TESEQ’s new NSG 3150 15 kV Combination Wave Surge generator

sets a new standard in the industry and represents the perfect solution for your immunity tests in compliance with IEC/EN 61000-4-5. Unique NSG 3150 capabilities enable users not only to perform tests according to exact standard requirements, but also to go beyond. The flexible repetition time setting which enables a significant reduction of test times is only one of many examples.


The perfect solution for testing outdoor applications

, the new NSG 3150 is used to test lighting, communication and energy distribution equipment, railways and protection systems and relays (e.g. IEC 60255-26).
The 15kV surge pulse voltage allows manufactures to reach new quality levels, which helps them to outperform competitors.
