Load Dump Generator with Clipping-module and battery switch

LD 200N200- 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 pulses have high energy with a high potential of destruction. These pulses having duration time in the range of hundreds of milliseconds. 

The LD 200N200 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 and battery switch, the LD 200N200 also generates negative- and clipped load dump pulses as per international standards as well as manufacturer requirements.

 Benefits
The LD 200N200 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 200N200 is a standalone tester including a 60V/200A 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.
