Load Dump Generators/Simulators

(Showing 7 of 7)

The EMC Shop stocks automotive load dump generators to test components to be used in electric vehicles (as well as gas-powered). Meet ISO 16750-2 and other industry standards as well as manufacturer standards or use software to customize or replicate voltage dropouts that you want to expose your device to.

AUTOMOTIVE LOAD DUMP TEST SETUP

Most of our customers will simply place the automotive load dump on a bench, ground the chassis, and be off and rolling. There are diagrams avaialble that specify spacing, placement, etc... We have found that in most cases, these aren't detrimental unless striving for full compliance.

Be sure the load dump generator and any external coupling devices are well grounded. Start testing at lower voltage levels to observe how your DUT responds as well as surrounding equipment in your test area. Your test setup may require you to move equipment and/or isolate your test area a bit more.

MENU OVERVIEW AUTOMOTIVE LOAD DUMP

OVERVIEW OF THE LOAD DUMP TEST

This test is a simulation of load dump transient, occurring in the event of a discharged battery being disconnected while the alternator is generating charging current and with other loads remaining on the alternator circuit at this moment; the load dump amplitude depends on the alternator speed and on the level of the alternator field excitation at the moment the battery is disconnected.

The pulse shape and parameters for an alternator with no centralized load dump suppression (pulse 5a).

The pulse shape and parameters for an alternator with centralized load dump suppression (pulse 5b).
