LIEBERT FS FLYWHEEL SYSTEM

Liebert UPS/Power Catalog - 7027 RELIABLE RIDE-THROUGH ENERGYSTORAGE, WITH OR WITHOUT BATTERIES

Enterprise UPS The Liebert FS flywheel DC energy storage system is designed to be a more efficient and reliable alternative to standard battery systems used with uninterruptible power supply (UPS)systems. The advanced, high-RPM, composite flywheel technology used in the Liebert FS provides 120 kW of instant ride-through DC power and voltage stabilization for approximately20 seconds—more than enough for the vast majority of electrical disturbances.The Liebert FS can be used as the sole back-up DC energy device or in conjunction with conventional battery strings or generator sets. When used along with batteries, the flywheelsystem will eliminate their use for short power fluctuations, helping to save capacity when it is needed for longer outages. It can also be used alone to provide ride-through power untilback-up generators come on line.The Liebert FS is engineered to support larger Liebert UPS systems, including the LiebertNpower and Liebert Series 610 models. A single flywheel can be sized to support UPS systemsup to 150 kVA. Multiple flywheel systems can operate in parallel to support larger systems.

System benefits include

â–  The compact, lightweight, and reliable Liebert FS flywheel system is safe and environmentally friendly.
â–  Offers a low installation cost, small footprint, low maintenance and long operating life.
â–  Unlike batteries, the Liebert FS uses no toxic metals and emits no explosive gases.
â–  Provides quick recharge, operates under a wide range of temperatures.
â–  Patented safety system provides a safe shutdown under all circumstances.
â–  When used with batteries, become the primary DC energy source of more than 98% of power disturbances, reserving the battery for longer outages, extending battery life and improving overall UPS output reliability.
â–  When used in a battery loss configuration, provides the needed short-term DC energy bridge to fast-start generator, or provides time for quick, orderly shutdown of critical operations.
