High Voltage On-board System Emulator LISN500

High Voltage On-board System Emulator LISN500

Emulation of the on-board electrical system impedance

The LISN500 (Line Impedance Stabilization Network)
is a network for emulating the DC impedance of the
vehicle on-board electrical system. The network is used
to perform measurements on components with highvoltage
DC supply on test benches under replicable
conditions. The LISN500 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 und 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
