The modular Teseq NSG 3060A conducted transient immunity test system adopts master-slave expandable architecture, integrating 6.6 kV combination surge, ring wave, 4.8 kV EFT burst and PQT voltage dip tests in one unit, complying with both IEC international EMC standards and North American ANSI C62.41 grid specifications. Equipped with an intuitive 7-inch touch screen, each pulse module can be calibrated separately without returning the whole machine. It supports expansions including pulsed magnetic field, 3-phase coupling network and telecom surge modules. Standalone manual operation and fully automatic PC sequence test are available, with multi-layer high-voltage safety protection. It is an all-in-one transient immunity tester for home appliances, industrial control, medical and PV products exported to North America and global markets.
