43 Simovert Masterdrive drives from 0.75 kW to 700 kW
A manufacturer of heat-laminated steel drums based in Germany wished to back up one of its production lines. Indeed, the electrical installation of the latter, which processes the manufacture of drums with a 98% pure alloy destined for top range automobiles, had not been updated since its first commissioning, in other words for more than 15 years. Within this context, it was imperative to back up the line drivers in order to extend the life of our client’s installation over the next 10 years.
