Introduction：
NNHV 8123-400R is the latest 400A high-voltage automotive electronics HV AN artificial network launched by Schwarzbeck, Germany, in 2024, which can support the testing of automotive electronic parts products with a maximum operating current of 400A and a maximum operating voltage of 1000V.
Differences and similarities between NNHV 8123-400R and NNHV 8123-400:
The NNHV 8123-400R and the NNHV 8123-400 are both high-voltage artificial networks, and they differ in only one way: they differ in impedance:
Impedance of NNHV 8123-400R: (5µH + 1 Ohm) || 50 Ohm;
Impedance of NNHV 8123-400: (5µH) || 50 Ohm;
As you can see, the design principles of the two ANs differ by a 1Ω series resistance that characterizes low-voltage LV ANs. So you can use NNHV 8123-400R to test older versions of CISPR25, GBT18655 and other standards. But it has higher voltage and current.
They have the same specifications except for the impedance parameter.

Meets criteria:
- ISO 11452-4
- CISPR 25 ed4.0 latest version
- BMW GS 95025-1
- GB/T 18655-2018
CISPR 25 is a standard number that applies to any electronic/electrical component on vehicles, boats, and internal combustion engines used for testing radio nuisance testing of vehicles, trailers, and installations to protect adjacent receivers on board the vehicle in proper working order. The name of the standard is: Vehicles, boats and internal combustion engines Radio disturbance characteristics Limits and methods of measurement for the protection of on-board receivers Vehicles, boats and internal combustion engines-Radio disturbance characteristics -Limits and methods of measurement for the protection of on-board receivers
Our standard GB 18655 is the Chinese translated version of CISPR25.
