Leroy Somer Digidrive SK AC drives-

Unlike the conservative European market of electrical equipment, where consumers are accustomed to trust only manufacturers whose equipment has proven itself for decades, the Russian market of drive equipment is oversaturated, it presents equipment from almost all world manufacturers, and the "novice consumer" faces a difficult question of choosing equipment.

In the current situation of the highest competition in the construction of automated electric drive systems, our engineers recommend using the principle of functional sufficiency of the equipment used - P'(F,S) the derivative of the dependence of cost on the functionality and reliability of the equipment and the Pareto principle. Following these guidelines when building an electric drive control system, it is possible to save up to 20-30% of the budget and get a reliable high-performance system.

Our engineers have made their choice in favor of Leroy Somer drive technology. To build control systems for high-precision and complex technological processes, we use high-performance drives Leroy Somer Unidrive SP, Digitax ST, Powerdrive MD series, for performing typical tasks without using a speed feedback loop (without feedback sensors) - multifunctional electric drives Leroy Somer series Digidrive SK.

The Digidrive SK AC electric drive is a reliable tool with one of the best cost–functionality-reliability ratios on the market, its modular design and built-in PLC make it possible to create high-performance control systems based on it.
