1. A compressor comprising:
- a sealed compressor shell housing a compressor pump unit, an electric motor for driving said compressor pump unit, and a low voltage powered valve associated with the compressor pump unit, said pump unit, said electric motor and said low voltage valve all being received within said compressor shell, said electric motor requiring a higher voltage power than said low voltage valve;
an inlet opening in said compressor shell for receiving an incoming high voltage electric power supply for powering said electric motor; and
a system for converting said incoming high voltage electric power to a low voltage electrical power, and feeding said low voltage electrical power to said low voltage valve, said system being received within said sealed compressor shell.

Abstract
Low voltage electrical power is supplied to a diagnostic control device in a sealed compressor. Electrical power is tapped from a high voltage power line and transformed to low voltage power that in turn operates the diagnostic control device. The diagnostic control device and the electric voltage transforming system are housed within the sealed compressor shell, thus eliminating the need for additional openings in the compressor shell. Other low voltage devices can be powered in this way.
