JUllin EMC TEST SYSTEM for AUTOMOTIVE ELECTRONICS KES SERIES . . . Transient Immunity Tester : KES7700 Series Voltage Variation Simulator : KES7400A Series Application Software for KES 7000 System : KES7100
Transient Immunity Tester KES7700 Series are transient surge tester that utilizes a compact unit system. A surge generator circuit is installed for each pulse unit as the tester meets the requirement of ISO7637-2, ISO7637-3, ISO16750-2, JASO D001, SAE J1113, and other standards. The KES7700 Series meets a broad range of independent automobile manufacturer standards as well. The ISO7637 standard specifies Pulse 1, Pulse 2a, and Pulse 3a/3b, while the ISO16750-2 standard specifies Pulse 5a/5b. Each pulse simulates the following: electromagnetic phenomena produced by electronic equipment joined by wire harnesses during an automobile's normal operation, electromagnetic coupling during switch opening and closing, and load dump surges produced by the alternator when the battery is disconnected. Each pulse also tests the tolerance of on-board electronic equipment. In this testing, malfunctions and breakdowns involving on-board electronic equipment are evaluated.

The KES7750, KES7751 generates test pulses 5a/5b required by the ISO and SAE standards. Test pulses 5a/5b are used to simulate the transient voltage that is produced when the battery is cut off from the operating alternator. An alternator having a transient voltage suppressor is tested with test pulse 5b, while test pulse 5a is used to test one that does not have such a suppressor.

SPEC80677/80678- Pulse 5b Load Dump Suppressor
ISO7637-2.2004 ISO16750-2,2010 Pulse5a/5b The SPEC80677/80678 are suppressors that generates pulse 5b required by ISO 7637-2.2004, ISO16750-2.2010 standard. When connected with the pulse 5a/5b module (KES7750), it lets you set a suppressed voltage of up to 100 V in steps of 0.1 V.
Features
■ 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. *The above applies only when Kikusui's pulse 5a/5b module (KES7750) or an amplifier circuit-based pulse 5a generator is used.

1.System components The KES7702/KES7703 main frame can be connected with up to 7 pulse modules (5 plug-in type modules + 2 external-connect type modules). By replacing pulse modules, it is possible to comply with various automotive manufacturer’s requirements, such as the ISO 7637-2 and JASO modules.  This system architecture also makes it easy to meet individual auto makers' test requirements.
2.Test reproducibility improvement
The KES7702/KES7703 mainframe are designed to simplify the setup of the test environment prescribed in the ISO7637-2 standards. Preparation of the test environment can lead to test reproducibility.
Output waveform stability
Placing the output system on the front surface and the power supply system and signal system on the rear surface made it possible to achieve stable transient surge output and communication control. Also, a bus bar was utilized for the output end. Since the input and communi- cation control systems of each unit are separated from the output lines, malfunction of the tester itself due to transient surges being output is less likely to occur.
Test reproducibility
Since the lower part of mainframe KES7702/KES7703 testers is an SG unit, braided wire and other ground cables are unnecessary as a connection with a ground plane can be made.Also, the output terminal is set at a height of 50 mm from the ground plane (reference ground surface) as prescribed in the ISO7637-2 standards. 6

JASO standards are automotive standards established by the Society of Automotive Engineers of Japan. For environment tests, "D001: General Rules of Environmental Testing Methods for Automotive Electronic Equipment" is most generally utilized. Pulse units for performing "transient voltage characteristics tests" in this standard are available as an option. This pulse unit can perform tests conforming to JASO D001 standards by connecting to mainframe KES7702/KES7703 testers. ■ Replacing a pulse unit makes it easy to comply with JASO standards. ■ Recurrence interval: Settings from a minimum of 5.0 s are possible.
The application software KES7100 for the KES7000 system enables to control the KES7700 series and KES7400A series on the same platform. Test conditions for transient surge tests, voltage variations tests, and tests catering to individual automotive manufacturer's test requirements can be edited easily by using waveform libraries. Also, the arbitrary waveform generation function makes it possible to create various voltage variation waveforms. Furthermore, KES7100 enables to save user-created reports in CSV files.
Features
■ Up to 50 test conditions can be registered in a test execution list, and tests are carried out in accordance with the list. The test editing window allows user-defined test conditions to be registered in a database in advance. ■■ For transient surge testing, up to seven types of pulse modules can be controlled. ■ For voltage variations testing, up to four testers can be controlled for synchronous operation by communicating with a single tester. ■ In addition to those compliant with the ISO 7637-2.2004 standard, a variety of waveforms can be generated easily (for voltage variations testing). Besides the tests using ISO 7637-2.2004-compliant waveform libraries, tests catering to individual auto makers' test requirements can be conducted with ease by using the arbitrary waveform generation function and adding necessary waveform libraries.  For information about the supported standards, please contact us. ■■ The created test execution list can be saved in a file along with comments. A separate test execution list can be created for each type of device to be tested. ■ The result of the OK/NG judgment that the user makes at the end of each test can be saved in the execution list. A test record report (CSV-format file) can be created for each test registered in the execution list.  (These reports can be viewed and edited using spreadsheet software.) ■■ The RS-232C interface is supported for communication.
*2 ports are required when both transient immunity tester and voltage variation simulator are performed. The communication cable for RS232C is required for each port. It can be controlled simultaneously. The RS232C communication cable (1pc.) is included as a standard accessory.
