The EM Test NX7 Multifunctional Test Generator simulates burst, surge, power fail, ring wave and several other types of transient waveforms at a rated power of up to 7kV. EM Test NX7 immunity test systems are multifunctional transient test generators, their modular nature allowing test engineers to generate waveforms to the specifications of standards like IEC 61000-4-4, IEC 61000-4-5, IEC 61000-4-9, EN/IEC 61000-4-12 and more. A built-in single-phase CDN can extend to test three-phase devices via an automatically-controlled external CDN with the ability to operate at up to 200A per phase. Ideal for pre-compliance and full-compliance conducted immunity testing, as well as CE Marking testing processes, the EM Test NX7 Multifunctional Test Generator is conveniently small in size and operable by means of an accessible, 7" touchscreen or remotely with its Ethernet, USB or optical interfaces.
