  • The PFM61000-8 Series Magnetic Field Generator is a high-stability device developed by LISUN specifically for power frequency magnetic field immunity testing of electronic products. Its core positioning is to meet the demand for “power frequency magnetic field immunity evaluation” of electronic and electrical products in different scenarios. It can accurately replicate 50/60Hz power frequency magnetic field environments in scenarios such as residences, commercial premises, industrial plants, power plants, and medium-to-high voltage substations, providing standardized testing conditions for detecting the anti-interference capability of equipment under magnetic field interference.

    Typical Applications:
    • Information Technology (IT) Equipment Testing: In accordance with the standards GB/T 17626.8-2006 and IEC 61000-4-8:2020, it tests the immunity performance of equipment such as computers, servers, and routers under power frequency magnetic fields to ensure the stability of data transmission.
    • Medical Electronic Equipment Verification: For precision medical devices like electrocardiographs (ECGs) and monitors, it simulates the power frequency magnetic field environment in hospitals to evaluate the measurement accuracy of the equipment under magnetic field interference, meeting the EMC (Electromagnetic Compatibility) certification requirements for medical devices.
    • Automotive Electronics Immunity Testing: Based on the standard ISO 11452-8:2015, it tests the immunity of automotive components such as on-board ECUs (Electronic Control Units), navigation systems, and sensors to power frequency magnetic fields, preventing functional abnormalities caused by magnetic field interference during vehicle operation.
    • Power Equipment Testing: During the R&D of equipment used in the vicinity of substations and power plants (e.g., switchgear, metering instruments), it verifies the operational reliability of such equipment under strong power frequency magnetic field environments to ensure the stable operation of power systems.
    • Military Equipment Testing: In compliance with the standards GJB 151B-2013 and MIL-STD-461G, it tests the power frequency magnetic field immunity of military communication equipment and radar components to ensure operational effectiveness in complex electromagnetic environments.
    • Laboratory Certification Testing: It provides third-party testing institutions with power frequency magnetic field testing capabilities that comply with international standards, supporting the immunity testing 环节 of certification projects such as CE, FCC, and CCC for electronic and electrical products.
