Introduction:
NTFM 8131A is the latest AAN - Asymmetric Artificial Network produced by schwarzbeck, Germany. The device is represented by EUTTEST Shenzhen for sales and quotation services.
Also known as an impedance stabilization network T-ISN, the 8131A can be used to measure asymmetrical interference voltages on symmetrical data or telecommunication lines. Since 2002, the T-ISN has been used to measure asymmetrical interference voltages according to EN 55015 (electrical lighting equipment). In addition, it can be used for measurements according to CISPR 32. In contrast to the widely used T-ISN, the 8131 A is designed to withstand voltages up to 400 V AC and currents up to 3 A. The 8131 A is designed to withstand voltages up to 400 V AC and currents up to 3 A.
