(S.E.P.A.C., S.A. de C.V.) manufactured data monitoring systems and industrial process automation systems.

Principally the projects consisted of excitation systems for large alternators, equipment and supervisory controls for distribution and transmision networks, automation of hydro electrical plants, protection equipment and automation of electrical substations.

As of today, equipment supplied by SEPAC regulates nearly 20 % of the electrical capacity and telecontrols approximately 30 % of the electrical distribution in Mexico This success presents a solid platform in countries such as: Guatemala, Honduras, Costa Rica, Colombia, Paraguay, Chile and others.
