The power frequency magnetic field coil is designed for the power frequency magnetic field anti-interference test and meets the GB/T 17626.8 standard.
The power frequency magnetic field coil should produce the magnetic field strength corresponding to the selected test level and the specified uniformity, the magnetic field strength is up to 2KA/m, and the magnetic field strength can be customized.
The power frequency coil designed and manufactured by our company is made of non-metallic non-magnetic materials, and its cross section and mechanical structure are stable, which is beneficial to stabilize the coil during the test.
The coil has the appropriate size to enclose the EUT (in three mutually perpendicular directions)
According to the size of the EUT, the power frequency coils of different sizes can be customized, which can generate a uniform magnetic field in the entire desktop or vertical device volume, with a deviation of ±3dB.
When testing small devices such as (computer monitor, watt-hour meter, program-controlled transmitter, etc.), the standard size induction coil is a square with a side of 1m or a circle with a diameter of 1m. For standard square coils, the volume of the test area is 0.6m*0.6m*0.5m; when it is necessary to test larger volume equipment, standard size double coils can be used, and the volume of the test area is 0.6m*0.6m*1.0m.
In order to adapt to three mutually perpendicular magnetic field tests, the coil can be rotated from 90 to 360 degrees, and the test table can be rotated by 360 degrees.
Power frequency magnetic field coils with special requirements can be customized.
