Twin Sine Innovation

Twin Sine Innovation (TSI) builds AC power systems with no single point of failure, the best performing in the market.



No single point of failure

AC backup systems were previously fitted with static bypass switches which became a bottleneck and a single point of failure. In the event of failure, the critical AC load typically ceased, in most cases causing a service outage.


Based on a single, multi-functional module, Twin Sine Innovation (TSI) allows for truly redundant high efficiency, high availability, full scalability and easy handling. It meets the latest power system requirements of the IT, telecommunications and industrial sectors.



Thanks to these characteristics, a Twin Sine Innovation (TSI) based system will bring you lower operating expenses and reduced carbon impact.
