KES7711A
Pulse unit 1-12V
The Kikusui KES7711A is a Pulse‑1 module optimized for 12 V automotive systems, engineered to simulate load‑drop transient events — like those caused by disconnecting an inductive load — with high fidelity. Compared to other modules in the series, KES7711A offers a compact plug‑in form factor and specializes in low‑voltage automotive environments, making it ideal for testing 12 V electronics. It supports bipolar ±‑voltage pulses, adjustable output impedance, and flexible timing parameters, enabling a wide range of pulse simulations to match both standard (ISO/SAE) and manufacturer‑specific transient requirements.
