When the primary power source goes down, it’s vital that the UPS has a reliable DC power source to deliver energy to the critical loads. The Liebert FS stores energy kinetically via flywheel inertia rather than relying on chemical reactions of toxic lead and sulfuric acid.
Battery-Free
Solution For Use
With UPS Systems
Now you can get higher, more efficient UPS reliability by taking advantage of Liebert’s world-class flywheel energy storage technology. Liebert’s flywheel technology provides superior performance without the high cost of ownership and environmental impact associated with batteries.
Flywheel Technology Offers Many Advantages
The compact, lightweight, and reliable Liebert FS flywheel system is safe and environmentally friendly. It offers a low installation cost, small footprint, low maintenance and long operating life. It provides quick recharge and operates under a wide range of temperatures. The patented safety system provides a safe shutdown under all circumstances. The flywheel system’s unique operating features, such as rapid recharging and broad operating temperature range, allow the Liebert FS to be installed in applications where batteries have previously been ruled out.

Reliable ride-through energy storage, with or without batteries.
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 190 kW of instant ride-through DC power and voltage stabilization for approximately 10 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 flywheel system will eliminate their use for short power fluctuations, helping to extend life and save capacity for longer outages. It can also be used alone to provide ride-through power until back-up generators come on line.
The Liebert FS is engineered to support larger Liebert UPS systems, including the Liebert Npower and Liebert Series 610 models. A single flywheel can be sized to support UPS systems up to 225 kVA. Multiple flywheel systems can operate in parallel to support larger systems.
