Helmholtz coil for Low Frequency Magnetic Field Susceptibility Testing: EMC HLM-10 | EMC TEST
EMC HLM-10 Helmholtz coil for Low Frequency Magnetic Field Susceptibility Testing according to MIL-STD-461 RS01/RS101 and IEC/EN 61000-4-8 / 61000-4-9.
The EMC HLM-10 is a Helmholtz coil designed for Low Frequency Magnetic Field Susceptibility Testing on military equipment, subsystems and electronic devices under test. It is used to expose the Equipment Under Test (EUT) to a relatively uniform magnetic field and to support efficient EMC Qualification Tests.
The coil is specified for operation from DC to 30 MHz. According to the datasheet, it supports continuous magnetic field testing as well as pulsed testing with higher pulse current capability.
Advantages
- Relatively uniform magnetic field for reproducible susceptibility testing.
- Reduced EMC Qualification Test Time thanks to a defined test setup.
- Suitable for military EMC testing on equipment and subsystems.
- Adjustable specimen support with optic fibre feed-through for flexible EUT positioning.
- Suitable for continuous and pulsed magnetic field tests up to 20000 A/m in pulse mode.
