LD 200N - COMPACT HIGH-ENERGY LOAD DUMP GENERATOR

Load Dump pulses simulate the sudden disconnection (e.g. by corrosion) of the battery from the alternator while the
alternator is generating current to load the battery. 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, 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 (optional) the LD 200N
also generates clipped load dump pulses as per international standards as well as manufacturer requirements.
