This is a patented power supply optimization system. It is installed in series and, by means of controlling voltage levels, achieves a reduction in the consumption of electricity at customers’ facilities. It not only achieves significant savings in a facility’s power consumption, it also protects them from possible grid oscillations. The flexibility and innovation of our product does not only reduce consumption, it also offers a smart electricity control system, adapting to each company’s particularities and needs in a dynamic and continuous manner. “The voltage stabiliser manufactured and distributed by GESINNE has been tested and tried in the laboratory of the Department of Electrical Engineering of the University of Oviedo. The tests have shown that the equipment allows the transfer of power from the grid to the facility and is capable of regulating the output voltage without significantly altering the harmonic distortion conditions of the said voltage”.
