Teseq (Schaffner) NSG 2050 High Energy Pulse Generator System

The Teseq (Schaffner) NSG 2050 is a highly versatile, modular, multi-role EMC test facility adaptable to meet a wide variety of test specifications, from compliance with basic national and international standards, through detailed design characterisation to compliance with manufacturers’ own, more exacting EMC specifications. Its modularity offers each test lab a configuration to suit its test needs cost-effectively while remaining expandable so that, as test needs grow and change, System 2050 can be extended accordingly, thereby protecting investment.

Intelligent Mainframe

At the heart of System 2050 is the NSG 2050 mainframe unit, consisting of a micro-processor based control unit, a high voltage source and accommodation for user selected plug-in pulse networks. Each of the System 2050 plug-in modules and extension units comes complete with its own firmware, so that the system automatically recognises its presence and presents the user with the appropriate software menus and front-panel options. Intelligent control is effected either through the front panel controls and display or via a PC. Further, System 2050 is designed for inter-compatibility, using openarchitecture principles and modular Windows control software. As such, it can be combined seamlessly with any of Schaffner's specialist test and measurement instrumentation and with third party products, including radiated interference test equipment, in a complete ProfLine test system to meet the most demanding test needs.

A Complete Conducted Immunity Test System

System 2050 offers a complete set of plug-in networks for full compliance testing to basic, generic and product standards, for single-phase and threephase power lines as well as data and telecom lines. The mainframe unit and three plug-in networks (PNW 2055 surge and PNW 2225 fast transient pulse generators and PNW 2003 a power quality module) make up a complete, integrated system for testing susceptibility to conducted interference on single-phase power lines. System 2050 may include just one or several modules and each of these provides a self-contained test facility that requires no external coupling unit for single-phase power line immunity tests to the basic standard. As requirements change in the future, System 2050 remains expandable with further networks and extensions for new applications.

PNW 2050 provides high energy hybrid surge pulses of 1.2/50µs - 8/20µs with an extended voltage range as required by IEC, ANSIIEEE and many other standards. It is used with single- and 3-phase power-line coupling networks or data-line couplers. The network can also be used, in conjunction with an antenna, for pulsed magnetic field testing, e.g. to IEC 61000-4-9.
