Low‑Frequency Differential‑Mode Conducted Immunity Test System

Product No: LFCI61000-19

  • Specifications

  • The LFCI61000-19 Low-Frequency Differential-Mode Conducted Immunity Test System incorporates a signal source, power amplifier, and single-phase coupling/decoupling network. It is used to apply differential-mode conducted interference within the DC~180kHz frequency range to AC power ports, evaluating the immunity performance of electrical and electronic equipment to low-frequency differential-mode interference. It simulates on-site electromagnetic environments such as power grid switching disturbances, carrier communication, and differential-mode voltage and current disturbances at power ports caused by the operation of power electronic equipment. It is widely used for EMC type testing of products such as electricity meters, industrial control equipment, relays, power electronic devices, and instruments, as well as in third-party testing laboratories and enterprise R&D and quality control departments.
