KES7714
Pulse1-24V
The Kikusui KES7714 is a pulse‑generation module in the KES7700 series, built to simulate “Pulse 1” transients as defined by automotive EMC standards. It delivers high‑voltage bipolar pulses to emulate transient phenomena that occur when power supply is abruptly cut from an inductive load — such as wiring harnesses or motors. With adjustable voltage and impedance settings, plus a compact modular design and rugged build, KES7714 is ideal for EMC testing of automotive electronics, ensuring resilience to transient voltage spikes under real‑world conditions.
