Filter to Deal with Transformer Noise

I have a couple 12v cabinet light circuits, each run off independent transformers. I have added on/off insteon switches to control the power to the transformers. When one of the circuits is on, it is apparently creating noise that screws up other insteon devices in the circuit vicinity (i.e. they will not respond to ISY commands). So, my question is will the ACT-AF300 filter help in reducing the noise and hopefully cure the problem on the Insteon network (http://www.smarthome.com/4846/ACT-AF300 ... ter/p.aspx)? The product description references X-10, but not Insteon.

 

Thanks.

It is a low pass filter and the specification chart says 300Hz. So it would block X10 and Insteon power line frequency noise.

I had the exact same problem with a transformer for undercabinet lights. I used one of these http://www.ebay.com/itm/X10-PRO-XPF-20A ... 4176975cf1 and the problem was solved. I hard wired it directly to the transformer so I can still control the light with Insteon switches.

Awesome. I've ordered two and will wire them in. Not sure of the size, but am planning on putting into a junction box. BTW, does anyone's wife think they're nuts for doing all this?

They are pretty big, I don't know the exact size but they will not fit in a regular junction box.

Yes. Until it all works then mine understands.

Yeah, they are kind of bulky. They will fit in a triple wall gang box, but only if it is a deep box and your switches are very thin (pretty sure you aren't going to get an Insteon switch over it). They will fit in a 4 inch j-box like this. http://www.lowes.com/pd_70965-53911-521 ... facetInfo=

 

They are 3.5 inches in longest dimension. http://files.buyitsellit.com/8181/XPF.pdf
