SPEC 80677

Pulse 5b Load Dump Suppressor

The SPEC80677 is a load-dump suppressor module designed to generate Pulse 5b surge conditions for automotive EMC transient-immunity testing. It is ideal for evaluating the resilience of vehicle electronics against voltage spikes and load-dump events under real-world conditions.

Features

Key capabilities and advantages

  • Pulse 5b Load Dump Suppressor
  • Suppressed voltage: 100 V max. (settable in steps of 0.1 V)
  • The waveform required by the standard can be output accurately without changing the pulse width (td) that is set for pulse 5a.
  • Complied with ISO7637-2.2004 ISO16750-2.2010 Pulse5a/5b
