Automotive Supply Simulation Systems

Test pulses and voltage variations according to ISO standards and manufaCturer specifications

The modular simulation system ist very well designed to perform immunity tests with a pulse characteristic and with line coupling injection according to the following standards:

  • ISO 7637
  • ISO 16750-2
  • ISO 21848
  • as well as manufacturer specific standards from
    • Audi
    • BMW
    • Daimler Chrysler
    • Fiat
    • Ford
    • GMW
    • Mitsubishi
    • Nissan
    • PSA
    • Renault
    • SAE
    • VW


The system contains a 4-quadrant amplifier as a source and a test pulse generator including a software package SPS Automotive for testing and reporting.
As additional components a high voltage tester and a relay coupling field are available. The OPD is an add-on for the protection of prototype EUT's.


Operating ranges are:
U: 0…70V
I: 0…1000A
P: 0…30kW
for 12V, 24V and 48V systems
