Pulse 5a / 5b Generator ISS-7650 - NOISE LABORATORY CO.,LTD.

Automotive Transient Surge Simulator(ISS/JSS) Pulse 5a / 5b Generator ISS-7650

Pulse 5a : Simulation of load dump transient, occurring in the event of a discharged battery being disconnected while the alternator is generating charging current and with other loads remaining on the alternator circuit at this moment.
Pulse 5b : Simulation of the above load dump transient when a Zener diode is inserted to the battery route.

EMC Testing

Features

- ISO 7637-2 (2004) compliant pulse 5a
- Pulse 5a and Pulse 5b generating unit
- A built-in 60 V / 30 A Coupling Network allows independent operation.
- Equipped with a programmable clip circuit that can produce Pulse 5b clipped waveform in steps of 0.1 V without externally attaching a zener diode.
*The ISO standard requires pulse 5a and 5b have the same value for their td. Due to the effects of the integrated clip circuit, pulse 5b width is different from that of pulse 5a. Pulse 5b non-compliant to ISO 16750 (2012) Test B
