More easy: DIY short cable with Schaffner FN9244B (B: medical) + Schurter IEC C13. I have with 3A. 6A and 8A before two powerstrips. And a lot of Würth 150 kHz ferrites. SPAIN (EU): 230 Vac / 50 Hz -> we need less amperes (A) than in US (115 Vac / 60 Hz). This Schaffner has the better attenuation. Look at the PDF.
Hi! I got both of them locally, so they won't be very useful globally :( Enclosure is a DIY type you can get at electronic parts stores, the outlet I got from here: a.aliexpress.com/_EQdvWkN And the inlet would be something like that: a.aliexpress.com/_EGX3Dtx
Hi Greg - very nice video! I have a dedicated line in my house for my hi-fi but I may have to run some equipment from normal power outlets. So I think I will make some of these! Good tip about the shielded equipment power leads. I make my own power cables (Schuko and Swiss to IEC 10A) from Kimber 12TC clone cable with earthing and could imagine doing internal wiring with that (or 8TC) as its surface area is large (AWG 8 per conductor for 12TC) and notice an improvement in instantaneous response to transients. Question: why did you not use a metal box? Surely that would help more with shielding, wouldn't it? All the best, Rob in Switzerland
@@RobWhittlestone Hi Rob! I got plastic box for two reasons: 1. Safety (90%) 2. Price (10%) :) Metal one would work as faraday cage, but I wouldn't like any metal boxes in the cable mess I have sometimes behind my equipment rack. (I'm Tom btw but Greg also sounds nice ;) )
@@k4syxOh sorry Tom! I got you mixed up with the Virtual HiFi channel also in Poland - Poznan I think. Now I will try to get it right! My apologies! All the best, Rob in Switzerland
@@k4syx Yes. But their stuff (designed actualy for datacenters/racks) is probably cheapest option that in my opinion makes sense for AV/Audio. Their lead extension with surge protection and filter costs some 30 euros (used to be under 20 before covid...). Still the purpose built one will be better...
i bought a scaffner emi filter rated 20A and 250v instead of doing all this can i for example remove the wires that was going to my wall outlet ..live neutral and earth and connect it to the schaffner first then the output terminal connects to to the wall outlet? that way power is coming from the breaker then it gets filtered through the filter then i get filtered power directly in my wall mount i'll mount the schaffner very close to the wall outlet on the wall would it be safe ? the rated ampere is more than enough by the way for my equipment my equipements are only about 2000w and here in my country voltage is 240v 240v x 20A is 4800w so i should be safe right? or i need to also make sure the emi filter max voltage is 440v?
That would be exactly the same think (smart though not portable) but you need to have some ventilation room and standard wall mount boxes (at least in EU) are small, so you'd need something bigger
@k4syx yes there is ventilation when i use the room i turn the ac on i am using a dual box mount with uk plug and dual eu plug box so yes i would need 2 individual filters but is it doable? how can i ensure the emi filter is working the best as they can in such case? i will wall mount the fitlers and use trunking so the wires are not exposed in any way and maybe even add pure copper shielding sleeve to the wires
@@kuronekosan2830 You would mount them the same way as in this external box so they would be in series before the external power sockets. I meant some kind of ventilation in the wall mount box, some room for air - shouldnt get warm, but its better to stay in the safe side

I'd still use some enclosure for this but other than that - exactly!
The Schaffner ones are better but more expensive and a bit harder to get :)
Hi and thanks for the great tip.
Can you please send links to both inlet and enclosure?
Many thanks :)
Hi!

Enclosure is a DIY type you can get at electronic parts stores, the outlet I got from here:

And the inlet would be something like that:

@RobWhittlestone No problem, no harm done, I knew that you were mixing us ;)
How would I screw the connectors with the wire ? Do I need to mount those metal connectors at the end of the EMI filter wires ?
@@dezen7574 you need to have like 5-7mm of bare wire at the end of the filter cable and then you can just screw it in the socket wire mounts
The only thing better than polish Acar power lead extensions with EMI filter are your polish accented videos about how to build one :D
Thank you, I guess? :)
I don't think acars have that kind of EMI filters. AFAIK they have even simpler stuff.

Glad you've enjoyed!
i bought a scaffner emi filter rated 20A and 250v
instead of doing all this
can i for example remove the wires that was going to my wall outlet ..live neutral and earth and connect it to the schaffner first then the output terminal connects to to the wall outlet? that way power is coming from the breaker then it gets filtered through the filter then i get filtered power directly in my wall mount
i'll mount the schaffner very close to the wall outlet on the wall
would it be safe ? the rated ampere is more than enough by the way for my equipment
my equipements are only about 2000w
and here in my country voltage is 240v
240v x 20A is 4800w
so i should be safe right? or i need to also make sure the emi filter max voltage is 440v?
