...the next generation of green, battery-free UPS from Active Power

Modular UPS offering a wide range of modular and redundant backup power systems from 60 Hz / 300kW to 2400kW / 480V and 50Hz / 300 Kw to 2400kW / 380/400/415V. CLEANSOURCE® PLUS MMS offers 20% more power for the same footprint at the same price point.

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® PLUS MMS a clear alternative to modular static UPS systems reliant on battery storage. The 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.


Flywheel Technology

The CLEANSOURCE® PLUS MMS Modular UPS is based on Active Power’s Parallel Online Architecture which provides excellent isolation between input and output, while delivering Class 1 voltage regulation and dynamically cancelling effects of non-linear load harmonics.

This topology continuously provides online power protection to your operation, creating a clean sinusoidal output waveform and protecting critical operations against all nine IEEE power disturbances in a power dense, reliable, and energy efficient package.

Modular & Scalable Architecture

CLEANSOURCE® PLUS MMS G and Z series UPS systems are modular and capable of multiple redundancy levels (N+1, N+2,...). Customers may readily expand their systems in line with their own growth needs by adding further modules over time.
