Energy Storage System

Specification Overview

Wherever maximum productivity and system availability is critical, the Powerware PF2 battery-free energy flywheel storage system bridges the power gap, acting as a backup power or battery backup source during power quality or utility disturbances and acts as an effective UPS battery enhancement, battery backup system, or UPS battery replacement for traditional systems.

The Powerware PF2, a DC battery-free energy flywheel storage technology, is an integrated motor-generator-flywheel that stores kinetic energy in a constantly spinning, quiet, low friction steel disc. Compared to traditional UPS battery backup systems, the Powerware PF2 dramatically reduces space requirements, temperature restrictions, UPS battery replacement cycles, and maintenance costs while improving UPS system reliability and operational integrity.

The Powerware PF2 offers a number of benefits over traditional energy storage systems:

• Flexible siting
• Reduced maintenance cost
• Over 20 years of useful life
• High power density in a small footprint
• Non-toxic and non-corrosive
• Real-time monitoring of over 25 system parameters
• Only two terminal connections
• Remote monitoring by Powervision®
• Service by Global Services
