High Voltage Artificial Networks Intended for Conducted Emission Testing

Teseq recently introduced two high-voltage artificial networks designed for conducted emission tests and line termination during susceptibility tests for components. The HV-AN 150 and HV-AN S150 are suitable for use in automotive, military and airborne standards applications. These new line impedance stabilization networks (LISNs) offer a unique approach to e-mobility as well as help meet the need for increasing voltage and current values inside of vehicles.

The HV-AN 150 offers a universal solution with its jumper settings that covers the traditional way of testing as performed in CISPR 12, CISPR 25 and ISO 7637-2.  The combination of two networks in a shielded box enables the testing of shielded high voltage connections as seen in standard drafts of CISPR 12, CISPR 25 as well as ISO 7637-4.

Teseq's HV-AN S150 allows users a direct connection with a special high voltage connector that avoids any shielding problems. It offers a solution for high current, high voltage and shielded connections to equipment under test (EUT).  No additional shielding box is required when using this unit. It meets the draft versions of CISPR 12, CISPR 25 and ISO7637-4.

The HV-AN 150's frequency range and power ratings are related to the selected standard per jumper setting. For the existing low voltage part of CISPR 12, CISPR 25 and ISO 7637-2 is the range 100 kHz to 100 MHz, a max. DC voltage of 700 V and 150 A for 60 min. 1000 V DC are allowed for the high voltage part of the draft standards of CISPR 12, CISPR 25 and ISO 7637-4.  The datasheet helps with more details.
