Personal Dissipative Noise Attenuation


Modular Product The architecture of the PxDNA is that it can be deployed in a modular fashion. If a single PxDNA does not provide sufficient reduction of noise power, more units can be plugged into the same circuit.

Portable This PxDNA architecture is also portable. It allows you to change your “installation” easily, throughout the day, if you like. You can have a PxDNA in the office during the work day, bring it home and plug it in the living room in the early evening, and plug it into an outlet in the bedroom at night.

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 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 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 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.
