EM Test LD 200N Load Dump Generator for ISO 16750-2

The EMC Shop is an ISO 17025 accredited company. Rent or purchase an EM Test LD 200N Load Dump Generator for ISO 16750-2 for Automotive EMC Testing and Compliance.

The EM Test LD 200N 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.

EM Test LD 200N Benefits:

The EM Test LD 200N includes everything necessary to conduct fully compliant tests. It generates the required high-energy pulses as required by ISO 7637 and many other international and car manufacturer requirements discharging an energy storage capacitor into a passive pulseforming network. The decay of the waveform follows a double-exponential function as specified in Annex E of ISO 7637-2:2004.

The LD 200N is a standalone tester including a 60V/30A DC coupling/decoupling network but still can easily be integrated into a complete test set-up. Pre-programmed Standard Test routines allow highest user convenience. The FreeStyle mode allows the operator to easily generate individual Load Dump pulses setting time parameters and peak voltage as required.

The built-in CLD module enables the LD 200N to generate clipped load dump pulses as per various test requirements by setting time parameters and clipping levels as needed.
