KES7731
Pulse module 3a/3b
The Kikusui KES7731 is a specialized Pulse 5a/5b module for automotive EMC testing, distinguished by its high-current capability and enhanced waveform precision. Designed for integration with KES7700-series test systems, it generates standardized surge and load-dump waveforms while allowing fine adjustment of pulse width and repetition intervals. Ideal for testing electronic devices that require more stringent transient immunity validation compared to standard modules.
