Pulse 5a, 5b, 7

ISO 7637-2 Test pulses 5a and 5b

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).

The EMC shop has a variety of solutions for ISO 7637 Load Dump Pulse 5a, 5b, 7 compliance.
