Note that these tests are normally only required if the product is intended for use in a high magnetic field environment such as electrified railways, some industrial sites, hospitals, power generators or distribution transformer stations
|IEC61000-4-8||Power frequency magnetic field (eg: 50 and 60Hz)|
|IEC61000-4-9||Pulsed magnetic field (eg, Lightning strikes ,short circuit ‘events’, MRI scanners)|
The equipment required consists of a coil to generate the field, and a driver to supply the current to the coil.
The coil is normally an open coil size 1m x 1m square, supplied on a stand such that it can be supported and rotated to provide vertical and horizontal polarised fields.
HA 200 Specifications IEC 61000-4-8
- Power frequency magnetic fields acc. to IEC 61000-4-8
- Test levels 3 / 10 / 30 / 100 A/m; continuous 1 – 130 A/m
- Test level 1000 A/m short, with special transformer
For the pulsed magnetic field test, the Multi-CE5 mainframe generates the required pulse signals and is used in conjunction with the HI 200 coil unit. The HI 200 includes an interface to the Multi-CE5. The test is generated and controlled via the Multi-CE5 user interface.
