Noise Filters and Surge protectors

Since X10 uses the 120KHZ to communicate, can I use a Surge protector that
is rated 150Khz - 100Mhz instead of a plug-in filter for noise appliances?
Any input would be appreciated.

A surge protector is not the same thing as a plug-in filter. The units
are designed to perform different functions. You can use a surge protector
but it will not filter injected noise into the power line from attached devices.

I have no first hand experience here, but I have heard that plugging a noisy
appliance into a Tripp Lite Isobar Noise Filter & Surge Suppressor will
solve the problem. So, in this instance, the answer to your question is
YES. The Isobars look like normal power strip surge suppressors except that
they are known for their noise filtering properties. Also, they are a
little more expensive than normal power strips.

Hope that helps,
Jon

Thanks. The one's I was looking at was the Belkin because they say EMI/RFI
Filtering from 150Khts - 100Mhz. I will look at the ISObars. thanks.

Jack Ak provided the correct answer. There is some "filtering" but they don't
list how much. Furthermore filtering does not just stop at a particular
frequency. They simply set a given number and say filtering exists above this
number, but does not exist below this number. IOW they did not list dB per
decade or even dB of filtering. You really don't know that the filter does or
does not filter at 120 Khz - just that filtering is less at 120 Khz than at 150
Khz.

Even moreso is the purpose of the surge protector. It sounds like a power
strip which means that it probably is not effective for surge protecton anyway.
IOW it is designed to protect only from differential mode surges - surges that
typically don't exist.

If you want EMI/RFI filtering, is is available in modules for but a few bucks
in any electronic supply house. If you want surge protection, it is effective
when far from transistors and close to earth ground.

In short, I really don't understand why you were asking this question. Do you
want surge protection or EMI/RFI filtering? EMI/RFI filtering comes standard in
most properly designed electronics.

There is a patented designs that a power strip built-in with EMI filter and surge protector.
It could be good used to filter noisy and protect against to surges.

Could you please advise your rated current, vlotage? We will send for your reference later.

Hi James,

How about the Surge protector device which has noise filter device built in it.
It can meet your different requests at the same time. It has surge protection function and noise filtering. You do not need to use different devices to cover more space and money.

Contact me if you are interested in.
