System to test the immunity against magnetic fields acc.

MIL-461 E, ISO 11452-8, EN 61000-4-8, SAE J551-17 etc.

The system components will be individually configured for your requirements.

The LFPA 9733 B is a multi-purpose power amplifier

and can be used within the frequency range from

5 Hz to 1 MHz.

Typical applications are magnetic immunity testing

according to automotive standards or MIL-461 E or F.

The primary function of the compensation network NFCN 9734 is to provide a serial compensation of the inductance of Helmholtz coils (e.g. the HHS 5206-16). Thus the currents needed to produce the desired field strength can be achieved using relatively low voltages.

Low inductive precision high power shunt

1 x 0.25 Ohm / 800 W

1 x 1 Ohm / 800 W

2 x 0.5 Ohm / 400 W

respectively for best load matching at lower frequency end cooling fans

The hall probe HS 5136 can be used to measure magnetic field strengths for immunity tests according to MIL STD 461 and various automotive standards.

It measures static and dynamic magnetic fields with a field strength up to 9000 A/m. The HS 5136 is a transverse probe, i.e. the magnetic flux lines must be orthogonal to the longitudinal probe axis and orthogonal to the surface of the hall-element to obtain the maximum reading.
