The MFPO 9760 is a current transformer for the typical mains frequencies of 50 Hz / 60 Hz. It is used to feed the 1 m square induction coil FESP 5410-1. This coil can reach magnetic field strengths of 1000 A/m for a short time and 360 A/m continuously in its center. As this coil has only one turn it has relatively low inductance and can be used for fast signals in the time domain. On the other hand, a one-turn coil has a low coil factor and needs to be driven with hundreds of Ampere to reach the fields expected by these standards: IEC 61000-4-8, IEC 61000-4-9 und IEC 61000-4-10.

The side length of FESP 5410-1 is 1 m. Using the attached 22 mm tube it can be fixed to the glass fiber mast. There is an indexing adapter that allows rotating the coil. Every 90 degrees i.e. in horizontal or in a vertical position it will be stopped by a resilient pressure piece sliding into the indexing rail. The possible height adjustment range is ca. 250 to 1700 mm. If greater heights would be required this information should be communicated during the ordering process already. This would require longer cables which lead to higher resistances. By default, we design the system for the above-mentioned height adjustment range. Thinner or longer self-made cables might cause lower field strengths. The glass fiber mast allows rotating the FESP 5410-1 around its vertical axes.

The pulse generator which is built into MFPO 9760 allows defined “ON intervals” of 0.5…5.0 seconds. Other time intervals can be set by manually holding the start button longer. Alternatively, the interval can be set using the remote input.
