Abstract
A power measuring device is disclosed featuring the capability of converting resistively coupled load current and voltage signals to a digital pulse train whose frequency is proportional to the instantaneous power drawn. The digital pulse train can be optically coupled to a microcomputer-based display or process controller for conversion of the pulse train frequency to a power consumption indicating signal.
