I have not tried to order any, not sure who sells the cords. have not called the company yet either. WX7G does have a good point of view on the engineering of the cords. i just wanted to post the find.
i found the information in a samlex swithching power supply papers with the supply. i will quote what they say.
"Following additional guidelines may be followed to reduce the effects of RF noise:
Use additional appropriate AC radio frequency interference (RFI) power line filter immediately before the ac input to the power supply. Recommended:
Corcom Inc. (www.cor.com
) "Q" series. Filtered, ferrite coated cord set (www.emceupen.com
) is another source. These cord sets, with integral line interference filters, reduce common and differential mode interferences over a wide frequency range. Because they are shielded, they are also effective against radiated interferences. In addition to the built-in filter networks, the cable conductors are coated with an RF absorbing ferrite compound. This provides additional attenuation at high frequencies that is lacking in most reqular LC filters. The RF
absorption of the ferrite-coated cable avoids resonance's at high frequencies, reducing the conducted and radiated RF noises even further."
Maybe some one can tell us if they work.
