Comprehensive Testing Solutions

  • Charging Systems

  • Low- and High-Voltage Battery Systems

  • Radiated Immunity Testing

    • Transient Pulse Immunity Simulator

    The TPI-7637 series of transient pulse interference simulators integrate the pulse interference modules P1, P2a, P3a, P3b, P5a, P5b and the required coupling network into one device.
    TPI-7637 series simulators can meet international standards and the standard requirements of many global automobile manufacturers, and various waveform simulation generators can be customized by users. Depending on the model, the built-in coupling network can reach a maximum current of 50A. It has higher pulse voltage and frequency, and can freely set the rise and fall. It is used to find sensitive points of the product under test, far exceeding the requirements of the standard. The input of the built-in coupling network is connected to the output of the programmable power supply series products and can be used as a unified input port for the test object. Different simulators can be connected to a remote PC via Ethernet to form a complete test system.
    According to standards: ISO16750-2, ISO7637-2/-3, GB/T21437-2/-3, etc.
