- Outline
The KES7000 conductive immunity test system complies with ISO7637, which is one of an EMC test standards for automotive electronics. This system consists of the KES7700 Series transient immunity tester, KES7400 Series supply voltage variations tester, and KES7100 application software dedicated to the KES7000 system. This product configuration supports JASO standards and the specific test requirements of various auto makers with options or custom orders.
- Increasing importance of EMC tests for automotive electronics
+ Today, automobiles need to satisfy more strict social requirements of the environmental performance (e.g., improved fuel efficiency and measures for exhaust gas) and safety (e.g., on-board safety devices) as well as usability (e.g., driveability and comfort). It is immeasurable how much electronics are contributing to solutions of those requirements, and electronics is taking on more importance in the future.
+ Electronics has come into wide use not only in the automobile industry but also various other industries and our daily life. In particular, electronics has become widespread in the field of information communication in recent years. However, on the other hand, the widespread of electronics is yielding environments where electromagnetic waves are emitted around, and this may possibly cause confusion of telecommunication, bad influence on health, and other new misgivings. Therefore, automobile on-board electronic devices now need to be produced so that they have no unnecessary electromagnetic wave emission and are tolerant of electromagnetic waves, and the EMC tests are taking on more importance to satisfy those needs.
- Load dump suppressor for pulse 5b
The use of an amplifier circuit and a dedicated suppressor allows the system to generate waveforms that faithfully comply with the pertinent standards not only for pulse 5a required by ISO 7637 but also for pulse 5b.
- Built-in CDN* for high waveform reproducibility
The CDN connection form is an important factor which influences the quality of test waveforms. The KES7700 series has a 10- or 50-A CDN inside the main frame to implement high waveform reproducibility.
- Compact modular cabinet
The modular cabinet allows surge waveforms to be added with ease.
- Communication control lines separated from output lines for secure operation
The system has the output terminals on its front side and the power input and signal connectors on its rear side, thus providing the stable output of transient surge and communication control. For the output terminals, a bus-bar structure is adopted. Because the input and communication control lines are separated from the output lines in each module, the system does not malfunction due to the transient surge it outputs.
- Two types of CDNs available (60 V/50 A and 60 V/100 A)
The main frame contains a built-in CDN module supporting up to 100 A, thereby allowing a large-capacity test to be conducted in a single cabinet without using any external CDN.
