EMI Mitigation Kit

The GlobTek EMI kit is designed to facilitate the optimization of radiated emissions of an end use system coupled with a GlobTek power supply by adding ferrites to the output cord.

While all GlobTek power supplies meet all national and global EMI standards when connected to a resistive load, when coupled with certain systems, the combination will create unintentional high levels of radiated EMI which may exceed a system designer’s margin requirements or even exceed national and global limits.

Using this GlobTek kit, the system designer is able to select standard low-cost GlobTek materials rather than high-cost name-brand alternatives. Please note that GlobTek can also provide power supplies or cable assemblies with any brand of ferrite per user’s request should that be preferred.

It is recommended that the system designer keep this kit on hand when performing system level compliance. In the event that test results exceed expectations, a ferrite may be selected from the kit and applied to the output cord for trial-and-error testing until the desired results are achieved.

One or more ferrites may be added to the cable in any location provided it is at least 50 mm from either the molded strain relief or the molded connector. It is suggested to match the ferrite whose impedance is maximum at or near the frequency of concern in the system level testing.
