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 that might include the company’s UPS products as a component. Its products and solutions are based on its patented flywheel and power electronics technology and are designed to ensure continuity for data centers and other mission critical operations in the event of power disturbances. The company’s UPS products and solutions are designed to deliver continuous conditioned power during short-term power disturbances and outages, such as voltage sags and surges, and to 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. The company sells its flywheel-based UPS products, which it calls CleanSource UPS. In addition to selling stand-alone UPS products, the company’s MIS products integrate critical power components into a pre-packaged, purpose built enclosure that could be deployed by customers indoors or outdoors. The company’s MIS products could include its UPS products with other related equipment, including switchboards and automatic transfer switch; monitoring and control systems; fire detection; lighting; security; and air conditioning. Its CleanSource PowerHouse is a stand-alone power solution integrating a diesel generator and its UPS. The company also integrates and builds modular information technology (IT) infrastructure solutions to specification based on customer designs. These solutions are typically enclosures that have a built out interior, including electrical, cooling, monitoring, and other elements ready for the customer to add its IT racks and servers. Products UPS The company’s UPS products serve two primary functions. First, during normal operations they are continuously conditioning (cleaning) the incoming power from the utility and delivering ‘conditioned’ power to the client’s mission critical load. In this mode, the UPS regulates incoming utility power fluctuations in voltage and frequency. Second, if there is any interruption in the utility source, the UPS would provide temporary, or bridging power, until either the utility power is restored or an alternative generating source, such as a diesel generator, begins to provide power. CleanSource 300/250 Series UPS The company offers flywheel UPS product, integrating UPS power electronics with flywheel energy storage technology. The flywheel stores kinetic energy – energy produced by motion – by constantly spinning a compact rotor in a low friction environment. The company markets its flywheel-based UPS systems under the brand name CleanSource UPS rated at 300 kVA (kilo-Volt-Amps or power level) and 250 kVA for 480V and 400V applications, respectively. The company offers CleanSource UPS products in power configurations ranging approximately 1.5 million volt ampere with the ability to parallel these products to provide protected power. CleanSource HD UPS Series The company offers its CleanSource 750/625HD UPS in standalone modules rated at 750 kVA and 625 kVA for 480V and 400V applications, respectively. This system could be paralleled together to provide even more protected power. The company also offers an extended runtime option on CleanSource HD UPS that can provide customers up to 30 minutes of additional UPS runtime. MIS CleanSource PowerHouse For customers looking for a complete, integrated continuous power system, the company packages its CleanSource UPS along with switchboards and automatic transfer switch; monitoring and control systems; fire detection; lighting; security; and air conditioning into an integrated system. Due to the space efficiencies of its UPS products, the company is able to offer all of these components in a pre-packaged
