A Dynamic Rotary Uninterruptible Power Supply (DRUPS), also known as a Rotary UPS or RUPS, is a type of Uninterruptible Power Supply (UPS) system that utilizes kinetic energy storage, often from a flywheel, instead of batteries to provide continuous, conditioned power to critical loads during power outages and fluctuations. These systems are designed for high-reliability applications such as data centers, hospitals, and manufacturing processes where uninterrupted power is crucial.
