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
