Product description

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.

  • It is recommended that the VDS200N30 (item595) is hired along with the UCS 200N to act as the DC power source.
  • It is recommend that a laptop with the ISO Emtest software (Item124) is hired along with this item which allows the use of test software to control the generator and if required produce reports.

The UCS200N50 (Item593), VDS200N30 (Item594), LD200N (Item595) and the Autowave (Item596) are housed in cases which allow the assemble of a 19" rack as seen in the above photos in less than 10 mins to cover automotive transients including VM and ISO 7637 standards along with Def Stan 61-5 requirements.
