Abstract
A power supply, such as for powering and supplying communication data to devices connected with a low voltage line, is disclosed. For example, a converter device is coupled with an alternating current voltage source. The converter device down-converts an alternating current voltage to a direct current voltage. A switching device is in communication with the converter device. A processor is in communication with the switching device. The processor outputs a signal to the switching device. The switching device generates a square wave signal as a function of the signal from the processor and the direct current voltage. A remote device is controlled by data encoded in the square wave signal.
