The built-in flywheel energy storage takes up less than half the footprint of battery based systems, delivers efficiency up to 98% and lowers total cost of ownership by up to 40% over the life of the product. This field proven technology is based on a highly fault tolerant IGBT architecture designed to protect all critical loads, such as data centers, industrial processes and healthcare applications. Stored energy will provide ride-through up to 2 minutes depending upon configuration, making the CleanSource® XT MMS a clear alternative to modular static UPS systems reliant on battery storage. The XT MMS modular UPS system has more than enough energy storage for diesel starting and synchronization, even when paralleling generating sets. Elimination of batteries saves space and weight, reduces site testing and maintenance and removes the need for routine replacement after a few years of service life.


The Active Power CLEANSOURCE® XT SMS is the perfect combination of low total cost of ownership, superior reliability, and sustainability for any mission critical application. CLEANSOURCE® XT SMS provides 78% more runtime than the CleanSource 300, delivering one minute at typical industry loads.
