PATENTED HYBRID FILTER TECHNOLOGY
By
combining noise filtration and surge suppression technology, Juice Goose RX
Series products clean AC line noise and provide power protection on the hot,
neutral and ground power leads.
The Juice Goose Hybrid Filter circuitry reduces common mode (neutral to
ground) interference to less than 1 volt, while limiting normal mode
surges to under 10 volts. Plus, RX Series products feature
patented circuitry which protects from over voltages and
in-wall wiring faults.
All this at an economical price.
RX Series products use a Hybrid Filter Technology to
clean up both normal mode and common mode noise without
contaminating the ground. Normal Mode noise occurs between the line and neutral
leads of an electric power circuit. Common Mode occurs between either the line
or neutral and the safety ground lead.
The Hybrid Filter design uses a differential
transformer, capacitors and fast acting voltage clamping components.
Together that act as a low pass, "line conditioning" filter which performs
in much the same way as a series mode inductor. Yet, these components, along
with a capacitor between neutral and ground comprise the foundation of the
circuit which blocks common mode AC surges and line noise without adversely
affecting the ground line.

Notes to Table: N/L = information not listed in
company's published specifications. N/A = specification not
relevant to the particular product design (e.g. inductors and filters in the RX
Series do not "clamp" as do MOVs and "crowbar" type devices - and so, have no
technical response time). All information was obtained from published data
sheets or web sites and was believed to be accurate at the time of this
publication.
A LAB TEST
In an electronics testing and design laboratory, the RX
Series circuit and a Surgex SX 908 were subjected to the same high voltage
surge events using sophisticated surge generation and recording equipment. The
Juice Goose RX Series circuit outperformed Surgex in reducing the voltage let
through on both normal and common mode.
In the Normal
Mode Test both devices were subjected to a 6,000 volt surge. The RX Series
circuit allowed 3.7 volts to pass. The Surgex device allowed passage of 196.0
volts. In the Common
Mode Test, surge input voltage was reduced somewhat. The Juice
Goose circuit was subjected to a 3,000 volt surge. It allowed 0.287 volts
(i.e. 287 millivolts) to pass through. The Surgex device was subjected to one
third that amount of surge, 1,000 volts. It allowed a substantial 855.0 volts
through.

oscilloscopes at the time the tests were performed. Click here to download a pdf

Mode Test or the Common
