This relay switch is used for transient emission testing as specified in the ISO 7637-2 standard.
We also construct systems incorporating simulated power network circuits (LISN) and other components.

Simulator to generate Transient Pulse as required in FORD's EMC standard (EMC-CS-2009) for surge test onto automotive electronic devices. The generation waveforms are Pulse A1 / A2-1 / A2-2 / C1 / C2 surges standardized as RI130 & CI220, and Waveform F fluctuation standardized as CI260.

Simulator to reproduce various transient surge phenomena which are generated in a vehicle and required in JASO D001-94 General Rules of Environmental Testing Methods for Automotive Electronic Equipment established by The Society of Automotive Engineers of Japan Standard, and evaluate the immune resistibility of the equipped electronics devices against the surge.

Pulse 2b : Simulates transients from DC. motors acting as generators after the ignition is switched off.
Pulse 4 : Simulates supply voltage reduction caused by energizing the starter-motor circuits of internal combustion engines, excluding spikes associated with starting.

For a secure and safe mobility society
Technological innovation called “CASE” (Connected, Autonomous/Automated, Shared, Electric) isdiversifying at an unprecedented pace in automotive development. As the electrifi cation of automobilesprogresses, it is becoming increasingly important to check the EMC resistance of electronic devices invehicles due to mutual interference.
The ISS-7810 is a simulator that outputs transient surges required by the international standard ISO7637 for verifying the noise immunity tolerance of automotive electronic devices.
