KES7700 Series - Transient Immunity Tester

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. Eachpulse 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 producedby the alternator when the battery is disconnected. Each pulse also tests the tolerance of on-board electronic equipment. In thistesting, malfunctions and breakdowns involving on-board electronic equipment are evaluated.

■ Full compliance with ISO 7637-2.2004, ISO 7637-2.2011, ISO 7637-3.2007, ISO 16750-2.2010■ 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 thepertinent standards not only for pulse 5a required by ISO 7637 but also for pulse 5b.

■ Compact modular cabinet

The modular cabinet allows surge waveforms to be added with ease.

■ Output terminals provided at a height of 50mm above the floor level as specified in the ISO 7637-2 standard
Enhanced reproducibility■ 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 ina single cabinet without using any external CDN.

■ Dedicated software for condition setting and tester control■ JASO D001-94 pulse unit offered as an optional module

For other details such as compliance with test requirements of individual auto makers, please contact us.

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.

Pulse output bar

Placing the output system on the front surface and thepower supply system and signal system on the rearsurface 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 communication control systems of each unit are separated from theoutput lines, malfunction of the tester itself due totransient surges being output is less likely to occur.

KES7100 - Application Software for KES7000 system
The application software KES7100 for the KES7000 systemenables 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 individualautomotive manufacturer’s test requirements can be edited

easily by using waveform libraries. Also, the arbitrary waveformgeneration function makes it possible to create various voltage
variation waveforms. Furthermore, KES7100 enables to saveuser-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 bycommunicating 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 andedited using spreadsheet software.)■ The RS-232C interface is supported for communication.

RS232C**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 not
be controlled simultaneously. The RS232C communication cable (1pc.) is included as a standard accessory.

■ KES7100 Transient Surge Test
This waveform library is for transient surge testing. By default, it contains the waveforms specified by the ISO 7637-2 and JASO D001 standards.

■ KES7100 Voltage Variations Test
This waveform library is for voltage variations testing. By default, it contains the Pulse 2b and Pulse 4 waveforms specified by the ISO 7637-2 standard.

■ KES7100 Arbitrary Waveform Generation Function
A variety of waveforms can be generated by combining waveform parts.
Mode (AMP/SW)
Line (increase/decrease)
Sine wave (phase 0˚/180˚)
Square wave (phase 0˚/180˚)
Sine wave sweep (phase 0˚/180˚)
Square wave sweep (phase 0˚/180˚)
Exponential curve (decrease/increase)Semi-sine wave (phase 0˚/180˚)
Chopping wave (phase 0˚/180˚)
Vertical line (increase/increase)
Horizontal line / Sine wave (1/4 phase)■ KES7100 Auto Maker-Specific Waveform Library (Example)
For voltage variation waveforms required by automakers, pattern libraries are available (charged).
Complex requirements like the values of V (voltage)and T (variable time) are varied in steps can be
optionally added.
(An estimate is to be made through consultation.)
