MFS 100

Power Frequency and pulse magnetic field test system

The MFS 100 test system can be used to test
power frequency magnetic fields according to
IEC/EN 61000-4-8 and pulse magnetic field
according to IEC/EN 61000-4-9.

The MFS 100 is an accessory to either the
PSURGE 4010, PSURGE 8000 with PIM 100 surge
generators, or the ECOMPACT 4. It enables
magnetic field testing up to 1200 A/m.

Description

MFS 100 has a 1m x 1m square, single turn antenna.

A current of 1150A is needed to feed the coil to
produce a field of 1000A/m.

Magnetic field strength is defined at the center of a coil

with ±3dB variation.

Magnetic field is orthogonal to the coil plane.
Coil dimensions define the maximum EUT size as being

0.6m x 0.6m x 0.5m.

The MFS100 can be used for both vertical and
horizontal plane testing, by simply rotating the coil
antenna in its mounting on the stand.



Technical Specifications

The MFS100 is designed for EUTs up to 0.5m high.
To test larger EUTs, the antenna coil can be adjusted
in height on the mounting stand.

The MFS100 construction makes it easy to adjust the
antenna height.

The MFS 100 antenna can also be rotated through 90°
and placed alongside large EUTs to test all four faces
of the test object.
