Residential Dissipative Noise Attenuation – V2 and NEW V2X
The RxDNA-V2 model is designed for the commercial market or for the residential market where a residence may be in an area of town that is, or is close to, an industrial area of town. The DNA models reduce the dirty electricity by approximately the same amount – as a percent. They differ in the total amount of dirty electricity power that they can handle.

How To Select A DNA Model – An Analogy
Imagine that we have two water filters. One is designed for the home and one is designed for a major hotel. Both of these filters are designed to remove 90% of the contaminants.
The difference is that the hotel filter can handle a much larger volume of water as it is removing 90% of the contaminants.
In a similar way, all the DNA products remove approximately the same percent of dirty electricity, but the total volume of dirty electricity that any unit can handle is different.
The MxDNA handles the largest amount of dirty electricity and would probably be used mostly for industrial settings.
The RxDNA-V2 handles a medium amount of dirty electricity and would probably find its application in a commercial setting or a residential setting that might be in an industrial area of a city.
The RxDNA-V3LF is focused on reducing Dirty Electricity (DE) in a frequency range that is considerably lower than has been achieved before.
As always, this product has come about because of demands by our Dealers and Customers.
There is a increasing presence of Dirty Electricity (DE) energy below the usually-encountered frequency range.
Most residential, commercial and industrial solar and wind generation infrastructure use switching regulators, aka, Inverters, to change the DC (direct current) from the device (solar array or wind turbine) to AC that is used by our vast array of appliances, and they operate at a fundamental switch frequency in the range of 16 kHz to 25 kHz).
This produces DE at the fundamental switch frequency and harmonics of that frequency. In the case of a switching regulator (Inverter) that operates at 16 kHz, this will produce DE at:
The manufacturers of these switching converters are “blind” to this DE. They apparently do not measure it, specify it, or care about it.
Utility Wide Solar or Wind Infrastructure
Utility companies are increasingly deploying massive wind and solar infrastructure that serves an entire segment of a grid. This means that there is DE on the incoming power FROM the utility company.
Because of the massive nature of these alternative energy infrastructure, the frequencies used as the fundamental switch frequencies are substantially lower.
Examples: 3 kHz to 4 kHz
This means that the existing DNA Filters do not offer significant attenuation (reduction in DE) – at 3 to 4 kHz.
The new LF (low frequency) version of the DNA Line Filters, do indeed provide significant attenuation (reduction in DE) in the 3 to 4 kHz frequency range.
Other Sources of Low Frequency (LF) Dirty Electricity (DE)
As the senseless drive to “save energy” continues, there is an increasing use of switching circuit architectures for a variety of applications.
As an example, is the notorious “pool pump regulator/controller”. These systems chop the AC signal to control power and thereby control pump (motor) speed (volume of water flow). The DE that they produce is below the aforementioned 16 kHz to 25 kHz range.
Again, the existing line of DNA Filters will not provide significant attenuation (reduction in DE) at these frequency ranges. The new LF version of the DNA Filters does indeed provide significant attenuation at these Low Frequency ranges.
The PxDNA handles the smallest amount of dirty electricity and was designed for the residential market.
All DNA models have a self-protection mechanism, if it happens that you are subjecting that DNA model to an amount of dirty electricity that is too much (for that model).
The MxDNA and RxDNA-V2 have a mechanical circuit breaker that will disconnect that model from the AC line if there is too much dirty electricity applied to it. That circuit breaker is reset by pressing the reset button on the circuit breaker (on the DNA chassis).
The PxDNA has an electronic breaker. It is reset by unplugging the DNA unit from the AC line (the AC outlet) for 5 minutes then plugging it back in.

RxDNA-V2X, NEW PRODUCT
The RxDNA-V2X parallel filter, is the latest and by far, the effective parallel filtering device to reduce Dirty Electricity (DE). It is a significant variation (improved attenuation) on the existing RxDNA-V2 parallel filter (the latter of which is still available).
The creation of the RxDNA-V2X was driven by:
— the ever present “desire” by Dealers and Customers to have a simple “plug it in a wall socket” filter as opposed to a much more complicated and costly install of a DNA Line Filter by an Electrician.
— the usefulness of a Dealer being able to directly demonstrate what the filter product will do, i.e. for a specific parallel filter, prior to the Customer’s decision to acquire the filters, (the M7 Universal Test set notwithstanding).
— the ever present “desire” by Dealers and Customers to have the lowest cost filter that actually accomplishes useful attenuation (reduction) of DE, particularly from solar/wind inverters.
Many years ago, Dealers of our parallel products found that the attenuation that the parallel devices provided was not sufficient for solar/wind inverter applications when there were Electro-Sensitive people involved. This brought about the birth of the DNA Line Filter product line, which has proved to be very effective.
Recently, we at Palma Engineering have been contacted by many individuals who installed solar/wind systems, not knowing about DE, and are now in something of a panic, wanting to “do something” to reduce the DE fields that they are living within. And yes, they exhibited “sticker shock” at the cost and complication of a DNA Line Filter installation.
Birth of The RxDNA-V2X
Every known design principle, circuit architecture, and “trick in the book” was poured into the RxDNA-V2X. This new parallel filter (RxDNA-V2X) has significantly more attenuation of DE, than the existing Rx-DNA-V2. The RxDNA-V2X is specifically targeted at solar and wind applications, where 2 each RxDNA-V2X’s are installed at the Main circuit breaker panel, one on each of the incoming phases (aka Legs).
Computed Attenuation (Reduction) of DE
A complete mathematical model was composed of the new RxDNA-V2X filter and its performance was compared to the existing RxDNA-V2. The chart below is largely self explanatory.
NOTE: 8 db of additional attenuation (as shown in the chart below) that the RxDNA-V2X provides, represents a 531% further reduction in the DE, i.e. comparing the existing RxDNA-V2 attenuation, to the attenuation of the new RxDNA-V2X.
We envision that 2 standard outlets will be installed at the Main circuit breaker panel with one outlet on one phase, and the other outlet on the other phase. Then, a RxDNA-V2X will be plugged into each outlet. NOTE: total of 2 RxDNA-V2X’s.
