LD 200N Video Guides


Load Dump pulses simulate a sudden battery disconnection (e.g. by corrosion) from the alternator. Cause the lost of the battery load the alternator generates an overvoltage impulse. Such Load Dump pulses are high energy pulses with a high potential of destruction.

The LD 200N simulates these high energy pulses having a duration time in the range of hundreds of milliseconds. The LD 200N generates the Load Dump pulses as per ISO 7637, ISO 16750-2, SAE J1113, SAE J1455, JASO and many more manufacturer specification, e.g. Ford, Chrysler, Renault, PSA, NISSAN etc. By means of a built-in clipping circuit the LD 200N also generates clipped load dump pulses as per international standards as well as manufacturer requirements.
