X10 filter technology

Post by **Henk** » Tue Mar 10, 2009 3:41 pm

In case you will get new electronic equipment it is likely an X10 sucker ... so flatscreen televison, powersupply of laptop, etc.

So you will need more and more filters in your home to keep the X10 signal above the 200mV rating ......

In case you will open an X10 filter like the FM10 you will not find impressive technology .. it is just a coil (spoel) .... the price Euro 50+ is the only impressive part of this product .....

So my questions:

What is the mH rating of this coil in a FM10 ?
Any experience with home made filter ?
What will make a good filter ?
Any improvement putting two coils in serie
Conrad is selling coils (10 different ones) any part number getting close ?

If i believe this calculator (http://www.lautsprechershop.de/tools/in ... ule_en.htm) , the answer would be 0,64 mH.

The resistance is 0,2 Ohm per coil (just measured).

Last week I bought 3 lightning secured power diffuser boxes (stekkerdozen). A couple of days after installation of the first one, I noticed some Xanura switches not responding any more. Switching of the diffuser box solved the problem. Its the diffuser box itself that is causing the problem, turning it on (the diffuser box contains an on/off switch) empty and the problem returned, turning it off and the problem went away. I do not known if a filter would help in this situation because I am thinking the box lowers the impedance of the power line (I could offcourse use the PMIX35 I received last week to do so testing;-) ).

In the FM10 only a coil in serie and no resistor is present

Based on the online formula with 120KHz the inductance should be 0,83 mH and a resistor of 625 Ohm but is the resistor required ?

Conrad number 534455 is 16Amp and 1 mH - by removing some windings (17% ?) you may get closer to 0,83mH ?

Don't think my calculation is correct because i used the freq of 50 Hz, eventhough i can't recalculate based on this or do i. 120 KHz is the freq of X10 i guess?

The FM10 i got from Waakzaam Wonen (http://www.waakzaamwonen.nl/catalog/pro ... ter-plugin) does contain the components i have drawn. The resistance of 320 kOhm is correct (based on the color and measurement (it was 322) ).

Hope this can help you? I've had a study in small electronics, but almost completely forgotten the theory

Can we use this? :

I open the Holec AFX2 apparaat filter and I see only a coil .... so it looks like there is a difference with the FM10 ... it may help if you can put a picture of the inside i will try to get a picutre on line ...

Is there a difference in quality between the Xanura and FM10 filter?
The Xanura filter is almost twice the price???

I bought Xanura (in Italy) and price is lower than marmitek ! We know that eaton has been bought by marmitek, but production sites are (until now) different. Then a note about using x10 filters. I have much "noise" with the installation of four 220v linear actuators. With one filter i have a little improvement, my reseller suggest to place 2-3 filters in one after another mode (he gave me 3 to test, good guy !).
Do you have some (good) experience with such modality?

Hey,

I only have one Xanura filter placed before my HTPC, TV and
amplifier in the living room.

But since we have new washing and drying machines I have
problems with X10/A10 signals. I intend to but some more
filters and place all equipment behind filters.

Like:
- desktop pc
- wash- and drying machines
- router and harddisk in the cupboard (where my CM15 is placed)
- fridge and freezer

So that will make six. In the Netherlands a Xanura version is 77Euro,
Marmitek 45 and a brandless one 40 Euro. In case there is no real
difference it saves me more than 200 Euro!

PS:
Probably the filtering improves when 2 or 3 are placed before one
device, but I don't think I have that kind of signal problems :-/ !
Does anyone know the answer?!

I also use the FM10 filters and they work great for me, my X10 network is very stable.

Then I will choose the FM10...

Thanks,

Xanura filter costs 54 euro in Italy.

I had many noises over 220v coming from some electrical motors , i setup 2 xanura filters and put 1 signal amplifier svx10 , now since 2 days everythings work like a charm. ie since the first day of my domotica setup i have a lamp in the dinner room controlled by a x10 module, pc with homeseer was never able to on/off the lamp, only the remotes were able, now it works ! yes, i can

Good

Thats what i'm telling all along. X10 or better Xanura is a very reliable system if you have your powerline under control.
You should have filters on every major device, then its working like a charm.
Keep aware of every change you make on the powerline, thats a bit hard.
