SDM Series

SDM Series

The SDM Series is a high-reliability modular power solution designed for critical industrial applications. The system protects the load from all electrical disturbances in the input grid thanks to its input isolation transformer and fully controlled thyristor technology. Offering a flexible and scalable structure, this series allows for both power increase and redundant (N+1) operation through the parallel connection of modules. With smart battery management and a user-friendly LCD screen, it increases operational efficiency, while its compact design saves installation space.
