Active Power, Inc. designs, manufactures, sells and services flywheel-based uninterruptible power supply (UPS) products that use kinetic energy to provide short-term power as a cleaner alternative to electro-chemical battery-based energy storage. The Company also designs, manufactures, sells and services modular infrastructure solutions (MIS) that integrate critical power components into a pre-packaged, purpose built enclosure. The Company's UPS products and solutions deliver continuous conditioned power during short-term power disturbances and outages, such as voltage sags and surges, and provide ride-through power in the event of a utility failure, supporting operations until utility power is restored or a longer term alternative power source, such as a diesel generator, is started. Its flywheel-based UPS products are sold under the brand name, CleanSource UPS. The Company's MIS products include CleanSource PowerHouse and modular IT.
