Recently, our company has provided a medical equipment of large current power frequency magnetic field

test system MFS1000AS335 for Xi 'an High Voltage Electric Institute which is qualified acceptance and received consistent recognition and praise from leaders in the institute

and people in the society.


MFS1000AS335 is a specially designed high reliability large power frequency magnetic field simulator as

per the features and requirements of GB/T61000-8/IEC61000-4-8. It is applicable for EMC tests of medical

electrical equipment and electrical system. Power frequency magnetic field simulator is built-in high accuracy measurement acquisition system with over current, over voltage, over heat, automatic fault

alarm, etc. Many technologies fill the domestic blank.


This equipment with magnetic field intensity from 1A/m to 1000A/m adjustable, the step is 1A/m,  the size of

its magnetic field coil can reach 3m×3m which needs higher power to drive. The distortion rate of power

frequency current the simulator output can be controlled to be less than 5%, and the current of driving the

coil is by electronic switch control breakover and cut-off at 0 or 180 degree. The current has no oscillating

break-over and cut-off at these two angle, di/dt fully complies with the rise/fall rate of power frequency sine current to avoid additional high frequency magnetic field interference. At the same time, the even power frequency magnetic field test environment is also provided with a powerful

guarantee for the comparability and repeatability of EUT data results.
