Geoff Bradley Posted August 31, 2016 Share Posted August 31, 2016 I've just bought a Skyrc D100 charger and am confused about the 2 ferrite rings and little plastic clips ! included in the box. I know very little about ferrite rings but would have thought one would have be attached to the mains supply cable if required and perhaps the other to the 12v supply....as for the two plastic clip ! I'm scratching my head. Can anyone help....I should add that there is no mention of either of them in the handbook. Quote Link to comment Share on other sites More sharing options...

Denis Watkins Posted August 31, 2016 Share Posted August 31, 2016 Could you scale photograph them Geoff, next to a ruler They look enormous But are used to decouple signals along long cables Quote Link to comment Share on other sites More sharing options...
Bravo Delta Posted August 31, 2016 Share Posted August 31, 2016 These are ferrite noise suppressors , used to reduce electrical interference and clipped around cables . Quote Link to comment Share on other sites More sharing options...
Geoff Bradley Posted August 31, 2016 Author Share Posted August 31, 2016 Her's another pic Denis. I'm aware of that Bravo but which cables...and what are the plastic bits for ? Quote Link to comment Share on other sites More sharing options...
Denis Watkins Posted August 31, 2016 Share Posted August 31, 2016 These ferrites can only be for the AC charging cycle, the maker must be aware of interference, possibly to other household equipment. It is irregular, in that most of our gear causes no interference. A loop or loops are made in the output cable and the resulting ring of cable is clipped into the gutter shape of the ferrite. This interrupts any magnetic oscillations. The spacers keep cables apart, thus avoiding induction This is old school stuff, and maybe for countries where electrical tolerances are not as tight as our own Quote Link to comment Share on other sites More sharing options...
Geoff Bradley Posted September 1, 2016 Author Share Posted September 1, 2016 Thanks Denis.......I'll put em in my bits and bobs box ! Quote Link to comment Share on other sites More sharing options...
Martin Harris - Moderator Posted September 1, 2016 Share Posted September 1, 2016 Posted by Denis Watkins on 31/08/2016 22:11:13: The spacers keep cables apart, thus avoiding induction ...curious as to why they are polarity marked. Is there some cleverness concealed within the plastic? Quote Link to comment Share on other sites More sharing options...
Denis Watkins Posted September 1, 2016 Share Posted September 1, 2016 Any twisted or coiled cabled, will induce/cause flux/create magnetic field as current passes along it. Very useful sometimes but problematic when the change is not required. There is a remote chance that these objects were added to the box in error, as there is no mention of them in the manual.

Martin Harris - Moderator Posted September 1, 2016 Share Posted September 1, 2016 It was the polarity markings on the "spacers" I was wondering about! I can't imagine there's much harm from the inductance effects on the short cables between a charger and a battery being charged with the fairly well smoothed DC output?
