Testing System Meets New Immunity Testing Requirements

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

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

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

Disturbances are coupled onto cables in common mode (IEC/EN 61000-4-16) or differential mode (IEC/EN 61000-4-19) with continuous levels ranging from 1 V to 30 V. The NSG 4060 features an extension unit that expands the test range frequency to DC and the amplitude to 300 V 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 synchronization input. A remote control option is available through an optical RS232, RS232, LAN or USB.  Two USB, analog, 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 5.7" color display, high-resolution graphics to enable quick set-up of test procedures, as well as hard keys for frequently-used functions.
