    Companies demonstrated flywheel system/UPS operation

    Pentadyne Power and Emerson Network Power recently successfully demonstrated the Liebert FS flywheel power system with a 750kVA Liebert series 6110 UPS system. The FS system is the result of a partnership between the two companies to use Pentadyne’s Voltage Support system for Liebert UPS systems.

    The demonstration was conducted by both companies at Liebert’s facility in Delaware, Ohio, and involved eight of the company’s FS power systems, each capable of providing 120kW of power to the DC bus of the UPS, connected in parallel to the Liebert 610 system.

    The demonstration included a series of multiple, short-duration input outages and a sustained input outage. N+2 operation of the flywheel system was also demonstrated by sustaining the load while sequentially dropping one and then a second FS unit. In each case, the flywheel system provided the required power to operate the UPS at rated conditions.
