Liebert FS Flywheel DC Energy Storage
The Liebert FS flywheel DC energy storage system is an efficient and reliable alternative to standard battery systems used with a UPS. Liebert FS may be used as the sole back-up DC energy storage device or in conjunction with conventional battery strings and /or generator sets. Flywheels may be paralleled to provide for higher power requirements, longer runtimes, or for N+1 redundancy.
The Liebert FS flywheel DC energy storage system is designed to interface with larger Liebert UPS systems, from 20kVA to over 1MVA, including Liebert Npower, Liebert Series 300, Liebert Series 610, Liebert Series 600, Liebert NX and Liebert NXL models. A single Liebert FS battery-free unit provides 190 kW of DC power for 10 seconds, and more time at lower outputs, delivering a gradual handoff to a backup generator. Liebert FS units may be paralleled for higher power levels, longer run times or for N+1 redundancy.
