Damped Oscillating Magnetic Field Immunity Testing System

The DOMF61000-10 Damped Oscillating Magnetic Field Immunity Testing System employs high-precision digital control and power amplification technology to generate damped oscillating magnetic fields compliant with IEC 61000-4-10, ANSI C37.90, and EN 61000-4-10 standards. The system utilizes a single-loop coil to convert electrical signals into magnetic fields that accurately replicate transient electromagnetic interference characteristics observed during power system switching operations and equipment fault conditions.

This testing apparatus provides precise control over critical parameters including magnetic field strength, oscillation frequency, and attenuation characteristics, enabling comprehensive evaluation of equipment immunity. The DOMF61000-10 system is essential for compliance verification, quality assurance, and research & development applications across multiple industries including power system protection, industrial automation, automotive electronics, and medical devices.
