Haefely MSURGE Magnetic Impulse Field Test System

To be used for EMC Tests requiring impulse Magnetic Fields.

The MSURGE is an accessory to either the PSURGE 4010 or PSURGE 8000 with PIM 100 surge generators. It enables magnetic field testing up to 3000 A/m as required by IEC 61000-4-9.

The support stand can also be used for tests in accordance with IEC 61000-4-8 and IEC 61000-4-10.The magnetic field test set MSURGE consists of the magnetic coil and the connecting cables to the current surge generator.

MSURGE has a 1m x 1m square, single turn antenna. A current of 3600A is needed to feed the coil to produce a field of 3000A/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 MSURGE can be used for both vertical and horizontal plane testing, by simply rotating the coil antenna in its mounting on the (optional) stand.

AUTOMATIC TESTING
In conjunction with other Haefely EMC Test products, magnetic field testing can be fully or partially automated. Any Surge generator can be used together with the MSURGE to provide semiautomatic testing from the instrument front panel. Voltages can be programmed which correspond to a magnetic field strength at the center of the coil antenna. WinFEAT&R software used to control the Surge generators, means that impulse magnetic field testing can be semiautomatic with other EMC tests.

LARGE EUTs
The MSURGE 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 MSURGE construction makes it easy to adjust the antenna height. The MSURGE antenna can also be rotated through 90° and placed alongside large EUTs to test all four faces of the test object.
