NTFM 8131 Schwarzbeck CISPR15-ISN

Introduction：

NTFM 8131 is a conductive emission test ISN impedance stabilization network for CISPR 15 control terminals produced by Schwarzbeck, Germany and authorized to be sold by EUTTEST Shenzhen, which is generally used to connect the positive and negative power lines of the test EUT. Complies with standards CISPR 22 D1, EN55015-2002, CISPR 32, CISPR 15. circuit schematic diagram shown below:

Circuit schematic

The "Impedance Stabilization Network", also known as T-LISN, is used to measure asymmetrical interference voltages on symmetrical data or telecommunication lines. Since 2002, the T-LISN is used to measure asymmetrical EN 55015 (electrical lighting equipment) interference voltages. In addition, it can be used for measurements according to CISPR 32 and CISPR 15. In contrast to the widely used T-LISN, the 8131 is designed to withstand 400 V AC with a maximum current of 3 A. The 8131 is designed to withstand a maximum current of 3 A. The 8131 is also available with a maximum current of 3 A.

We also offer more available ISN impedance stabilization networks and AAN asymmetric artificial networks to choose from. Click on the links below to find out:
