AN-Series is an Artificial Network that electrically recreates the vehicular power-net impedance for component tests of voltage class B (high voltage) components in laboratories and test-benches. The AN-Series uses an analog system with a bandwidth covering up to 150 kHz.  

An artificial network like the AN-Series is crucial for the proper testing of all voltage class B component in both hybrid and electric vehicles. Generated DUT interferences like ripple, dynamics, spikes and other higher frequency noise is correctly absorbed and reflected by the Artificial Network, recreating conditions similar to that in a vehicular high voltage power-net. 

The composition of a DC source and an HV on-board network replica of EN Impedanz enables simple and correct testing of HV components and DC charging stations.
