KES7750

Pulse module 5a/5b

The Kikusui KES7750 is a pulse‑generation module for automotive EMC transient immunity testing, designed to produce Pulse 5a/5b waveforms as defined in automotive surge standards. It enables accurate simulation of load‑dump and surge events for evaluating the robustness of vehicle electronic components under real‑world transient conditions.
