High Voltage On-board System Emulator LISN1000

High Voltage On-board System Emulator LISN1000

Emulation of the on-board electrical system impedance

The LISN1000 (Line Impedance Stabilization Network) is a
network for emulating the DC impedance of the vehicle onboard
electrical system. The network is used to perform measurements
on components with high-voltage DC supply on test
benches under replicable conditions. The LISN1000 fulfils the
requirements of the standards for electrically powered road
vehicles ISO21498, MBN11123 and comparable standards.

Main features:

  • The resistance values can be changed by jumpers between 2 x 25 mΩ, 2 x 50 mΩ, 2 x 75 mΩ and
    2 x 100 mΩ
  • Decoupling capacitor at the DC input
  • Water cooling
  • Active discharge of the decoupling capacitor, controlled by the test bench via CAN or emergency stop
  • Measurement of internal heat sink and water temperatures with limit value monitoring
  • Display for showing status messages and the measured temperatures
  • Galvanically isolated CAN interface for reading out temperatures, error messages and controlling the discharge
