As digital infrastructure, healthcare systems, and industrial automation become increasingly sensitive to power disturbances, ensuring uninterrupted power availability has emerged as a core design requirement. Socomec is addressing this need with its STATYS range of Static Transfer Systems (STS), designed to provide ultra-fast, semiconductor-based source transfer for mission-critical electrical loads.
Semiconductor-Based Power Source Transfer
Unlike conventional automatic transfer switches that rely on electromechanical components, Socomec’s STATYS STS uses silicon-controlled rectifiers (SCRs) to perform source transfer between two independent AC power supplies. This solid-state design enables transfer times typically within a quarter of an electrical cycle, effectively eliminating supply interruption for sensitive loads such as IT servers, medical equipment, and industrial control systems.
The system continuously monitors both power sources, analyzing parameters such as voltage stability, frequency, phase alignment, and harmonic conditions. In the event of a source anomaly or failure, the STS automatically isolates the affected input and transfers the load to the alternative source with seamless continuity.
Designed for High Availability Architectures
The STATYS product family supports a wide range of current ratings and installation formats, from rack-mounted units for localized redundancy to high-current chassis and cabinet solutions for centralized power distribution. With capacities extending into the kiloampere range, the systems are designed to support data centers, hospitals, telecom infrastructure, and large industrial facilities where downtime is unacceptable.
A key differentiator is Socomec’s Transformer Switching Management technology, which controls the transfer of inductive loads such as downstream transformers. This mitigates inrush currents and transient stresses, ensuring stable operation even in complex power distribution architectures such as catcher-type redundancy schemes commonly used in data centers.
By eliminating mechanical wear points, the STATYS STS improves long-term reliability while reducing maintenance demands. Modular construction allows scalability and integration into existing electrical architectures without requiring full system shutdowns. The solutions are designed in compliance with applicable international standards for safety, performance, and electromagnetic compatibility, supporting deployment across global markets.
Applications of STATYS STS
STATYS Static Transfer Systems are particularly well-suited for environments where power availability directly impacts safety, operational continuity, or revenue. These include large-scale data centers, healthcare facilities, transport and telecom infrastructure, and industrial automation systems operating in challenging grid conditions.
