Power transformers are widely used for voltage conversion. Power transformers provide rated voltage and current to electric and electronic devices while isolating those devices from the AC current mains. Power transformers convert an alternating current power supply of the type available in homes, offices, hotels, and the like via an ordinary wall outlet to a direct current power supply compatible with electronic devices, such as telephones, answering machines, computers, and radios. Power transformers process far greater influxes of electric current and voltages than distribution type transformers. Power transformers are normally designed to conform to unique substation requirements. To provide the regulated power supply, the transformer includes a power converting circuit within the housing having a male connector positioned thereon. The male connector is for a connection to a female connector of a main power supply wall outlet.
