Magnetic Field Generator
The IMU Series of immunity generators from EMC Partner can be equipped to perform power frequency magnetic field tests in full compliance with IEC 61000-4-8 and similar standards. A built-in variac (autotransformer) is used as the current source. The single turn MF1000-1, MF1000-2 or MF1000-3 magnetic field antenna is then connected to the output of the variac to deliver a magnetic field up to 160 A/m continuous or 1,100 A/m short duration.
The desired magnetic field test level is entered directly in A/m in the touch screen controller of the IMU generator and the variac adjusts its position accordingly to deliver the required current to the antenna. Alternatively, tests can be remotely controlled through TEMA3000 automation software.

Standards
- IEC 61000-4-8
- IEC 61000-6-1
- IEC 61000-6-2
Magnetic Field Antennas
MF1000-1* – 1m x 1m standard antenna
MF1000-2 – 1m x 2.6m antenna for equipment racks
MF1000-3* – 1m x 1m antenna for short duration tests
*Stands are available to conveniently rotate the antenna in the X, Y and Z orientations
The same MF1000-1 and MF1000-2 magnetic field antennas are also used for compliance to IEC 61000-4-9 pulsed magnetic fields when connected to the IMU generator surge output and IEC 61000-4-10 damped oscillatory magnetic fields when connected to a DOW3000 or DOW-CG1 damped oscillatory wave generator.
