Comprehensive Testing Solutions

  • Charging Systems

  • Low- and High-Voltage Battery Systems

  • Radiated Immunity Testing

    • Wire Harness Open-Circuit and Short-Circuit Simulator

    The OCL-0150 wire harness on-off and short-circuit simulator is designed based on the relevant provisions of GBT45120-2024, ISO16750-2(2023), and other standards regarding signal line open circuits and short circuits. It can handle simultaneous or independent testing of up to 50 lines. It greatly simplifies the complicated wiring and repeated experimental work of testers. It can use one-time wiring to automatically complete the standard test work on line on-off and short-circuit of power lines and ground wires. It has functions such as real-time or single-channel voltage and current monitoring, and automatic generation of reports on related data. Single-step test time can be freely set from 20mS to 10000S. It can handle the current of each channel not exceeding 10A, and the current of multiple lines at the same time not exceeding 50A.
