Test system meets new immunity testing requirements

Paul Boughton

Teseq announces a test system that meets the new requirements for immunity testing to low frequency disturbances in the frequency range of 15Hz to 150kHz.

The NSG 4060 complies with current testing standards including EN 61326-3-1, IEC 61850-3, IEC 60255-22-7, IEC 60533/IEC 60945, IEC 61000-4-16 and IEC 61000-4-19.

Suitable for use by manufacturers of smart electrical meters, industrial circuit breakers, industrial Ethernet and shipboard equipment, the NSG 4060 is a robust system with a host of features and a best in class user interface with an intuitive front panel that enables the unit to run fully compliant tests without a PC. It accurately tests low frequency immunity in common and differential mode.

The new test system features a full range of verification accessories and ensures compatibility of components at a competitive price. These accessories allow in-house confidence checking of differential CDN (CDND).

Disturbances are coupled onto cables in common mode (IEC/EN 61000-4-16) with continuous levels up to 33V or differential mode (IEC/EN 61000-4-19) with levels  up to 22V / 4.5A. The NSG 4060 features an extension unit that expands the test range frequency to DC and the amplitude to 300V for short term tests.

This new unit, which combines a signal generator and integrated power amplifier, features a user port for four TTL inputs and four TTL outputs as well as supply voltages for individual monitoring and control applications.  There are also ports for generator output, system and coupling network control as well as phase synchronisation input.

A remote control option is available through an optical RS232, RS232, LAN or USB.  Two USB, analogue, digital and optical EUT monitoring inputs and external modulation input come standard on each unit.

The NSG 4060 shares the same chassis and user interface as the popular NSG 4070 RF conducted immunity system, featuring the same user-friendly 5.7in colour display, superb graphics to enable quick and user-friendly set-up of test procedures, as well as hard keys for important functions.

A user manual with extensive set-up diagrams and instructions is included with each unit.
