- 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
SPEC80678
Pulse 5b Load Dump Suppressor
The SPEC80678 is an automotive EMC surge module designed to generate Pulse 5b load-dump and surge conditions for transient-immunity testing. It is ideal for evaluating the resilience of vehicle electronic components against high-current surges and voltage load-dump events under realistic automotive conditions.
