Tester meets new immunity testing reqs

Testing at frequencies from 15 Hz to 150 kHz, the NSG 4060 test system meets the new requirements to test for  immunity to low frequency disturbances, and 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. Suited for use by manufacturers of smart electrical meters, industrial circuit breakers, industrial Ethernet, and shipboard equipment, the NSG 4060 offers extensive features and a user interface/front panel that lets users run fully compliant tests without a PC.

Combining a signal generator and integral power amplifier, the system, which tests low frequency immunity in common and differential mode, features a full range of verification accessories that 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 33 V or differential mode (IEC/EN 61000-4-19) with  levels  up to 22 V / 4.5 A. The NSG 4060 features an extension unit that expands the test range to dc and the amplitude to 330 V for short term tests.
