The PowerSync Network consists of eTactica's Gateway (EG-200), Power Meter (EM-SC/FC) and Power Bar (EB-3XX). The Gateway synchronizes voltage measurements on mains with current measurements on branches, allowing power and other quantities per branch to be calculated. This data can then be delivered to any configured service. The PowerSync Network can measure up to 3000A on mains and 63A on branches (extendable to 500A). The PowerSync Network can be scaled to further branches via addition of more Power Bars.
