Plug in regulating power supply

DETAILED DESCRIPTION What we claim is: 1.
A plug in voltage regulating power supply comprising, a transformer having an input and output winding with a pair of plug in terminals connected to the input winding, an electronic voltage regulator connected to the output winding of the transformer and energized thereby adapted to produce a regulated output voltage, said voltage regulator having at least one electronic element generating significant heat, a thermoplastic enclosure mounting said transformer and said voltage regulator and enclosing the same with said plug in terminals of said transformer extending therethrough; and a heat sink mounting said heat generating electronic element apart from said transformer and said voltage regulator and positioned within the thermoplastic enclosure and against one surface thereof to distribute the heat generated by said electronic element throughout said surface of said enclosure.
2.
The plug in regulating power supply of claim 1 in which the transformer is the step down voltage regulating transformer producing a low voltage output therefrom.
3.
.
The plug in regulating power supply of claim 2 in which said transformer includes a core structure formed of a pair of opposed double "E" type core members providing a large window opening for the input and output windings and a saturating winding to be distributed thereon and, defining a low thickness profile enclosed in said enclosure.
4.
The plug in regulating power supply of claim 1 in which the electronic element of the electronic voltage regulator is a single power transistor providing from the regulated power supply a regulated DC low voltage output.
5.
The plug in regulating power supply of claim 3 in which the thermoplastic enclosure is a sealed unit enclosing a transformer and electronic voltage regulator providing passage therethrough for the plug in terminals of the transformer and output terminals from the voltage regulator.
6.
The plug in requlating power supply of claim 5 in which the thermoplastic enclosure includes a flange projection having an aperture therethrough located adjacent that portion of the enclosure through which the plug in terminals extend and adapted to receive a mounting screw to secure the plug in regulating power supply on an electrical recepticle
