New ISO 7637 Standard Automotive Transient Surge Simulator
ISS-7810 / ISS-7820 / ISS-7821
Technological innovation called “CASE” (Connected, Autonomous/Automated, Shared, Electric) is diversifying at an unprecedented pace in automotive development. As the electrification of automobiles progresses, it is becoming increasingly important to check the EMC resistance of electronic devices in vehicles due to mutual interference.
The ISS-7810 is a simulator that outputs transient surges required by the international standard ISO 7637 for verifying the noise immunity tolerance of automotive electronic devices.
- Perform testing in compliance with ISO 7637-2 and ISO 7637-3 Standards.
- Perform various 12V / 24V tests.
- Mounted on a space-saving vertical rack.
- A wide variety of options such as coupling clamps and waveform verification is available.
- The included remote control software allows individual test sequences setting.
- Highly operable and intuitively user-friendly integrated remote control software.
System Overview
The ISS-7810 is a rack-mounted test system with separate pulse units. It has excellent expandability and can be equipped with pulse 5a/5b and Slow pulse +/- if necessary (*1).
In addition, sequence tests and reports can be created by controlling the entire system with software using a PC.
