The Active Power CLEANSOURCE PLUS MMS UPS, 300kW to 2400kW, 480V, offers a wide range of modular and redundant backup power systems and offers 20% more power within the same footprint. These systems, capable of multiple redundancy levels, can be readily expanded by adding further modules as needed. In total, 8 modules can operate in a single system, providing up to 2400kW of high efficiency, battery-free UPS power.
The built-in flywheel energy storage delivers efficiency up to 98% and lowers total cost of ownership by up to 40%. This field-proven technology is based on a highly fault tolerant IGBT architecture that is designed to protect all critical loads, such as data centers, industrial processes and healthcare applications. These models are Made in the USA.
Stored energy will provide ride-through for up to 2 minutes depending upon configuration, making the CLEANSOURCE PLUS MMS a clear alternative to modular static UPS systems with batteries. The MMS modular 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.
