    • Automotive Transient Emissions Test System

    The automotive transient disturbance test system TES-50 is suitable for transient conducted emission tests required by standards ISO 7637-2 and GB/T 21437-2. TES-50-MS is a standard automotive relay designed to measure transient emissions with amplitudes exceeding 500V. TES-50-ES is a semiconductor electronic switch used to measure transient emissions with an amplitude less than 500V.
    According to standards: ISO 7637-2, GB/T 21437-2, etc.
