The document describes a product called the Module-Optimizer ECOD, which allows optimization of voltage within international quality standards to save up to 10% on energy consumption. It monitors input and output power quality, measures consumption over time, and operates on three phases simultaneously. It increases equipment lifetime, is not sensitive to instantaneous loads, and has a large display. Its goals are to regulate voltage without harmonics while meeting output standards and improving efficiency for motors and reactive loads. It provides savings of 10% or more and is lightweight, durable, easy to install and monitor remotely, with quick repair and ROI. It works by efficiently regulating voltage without interrupting the circuit or distorting waves, and switching in under 20ms. Implementation examples provided
