Due to the overwhelming acceptance of Electronic Converters (7300, 7400, and 500 Series units), and the decreasing demand for Linear/Ferro-resonant Converters (6300, 3200, and 900 Series), Parallax Power Components has announced that it has discontinued the production of its Linear/Ferro-resonant series converters.
