These line impedance stabilisation networks (LISNs) offer a unique approach to e-mobility as well as helping to meet the need for increasing voltage and current values within vehicles. Via jumper settings, Teseq’s HV-AN 150 offers a universal solution 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.
The Teseq 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 the frequency range is 100 kHz to 100 MHz, a maximum DC voltage of 700V and 150A for 60 min. 1000 VDC is allowed for the high voltage part of the draft standards of CISPR 12, CISPR 25 and ISO 7637-4.
