Product No: LIS-LSCS-1730
The LIS-LSCS-1730 Automotive Wire Harness Open‑Short Simulator is a dedicated simulation device for automotive electronic and electrical testing. It simulates standardized operating conditions such as open circuits, short circuits, power supply short circuits, ground short circuits, and connector interruptions on signal lines and load circuits, meeting the stringent testing requirements of GB national standards, ISO international standards, and major automakers for circuit reliability and protection performance. The device supports multi-channel independent or synchronous control, allowing for complete testing with a single wiring setup, significantly simplifying manual operation and improving testing efficiency and consistency.
The LIS-LSCS-1730 Automotive Wire Harness Open‑Short Simulator incorporates standard test procedures, supporting programmable settings for action time, number of cycles, and number of test steps. Combined with real-time voltage and current monitoring and automatic test report generation, it can be widely used in the R&D verification, certification testing, and production line quality control of electronic and electrical components in passenger cars and commercial vehicles, and is seamlessly compatible with various testing systems.
