Abstract:
A device for powering an external luminous tube load comprising:an device chassis; an external ground terminal electrically connected to define a chassis ground; input terminal means operable to receive a source of power; a transformer mounted to the chassis, the transformer having a core, a primary winding electrically connected to the input terminal means and at least one secondary winding, the secondary winding having at least two electrical endpoints, the to transformer core and secondary endpoints being electrically isolated from the chassis ground; at least two high voltage external output terminals electrically connectable to the luminous tube load, the high voltage external output terminals electrically connected to the secondary endpoints; and an external midpoint terminal electrically adapted to provide a midpoint wiring location for the external luminous tube load, the external midpoint terminal electrically isolated from the chassis ground and the secondary winding.
