Pentadyne selected to provide a flywheel power system for NASA

Chatsworth, Calif., Nov. 5, 2003 — The new Pentadyne Voltage Support Solution™ flywheel power system has been selected by Call Henry, Inc. to provide voltage support and backup power for the flywheel technology research lab at the NASA Glenn Research Center.

The Pentadyne system will be integrated with a 50 kVA (100 Amp, 3-phase 120/208 output) uninterruptible power supply (UPS) to serve the research lab requirements. This effort, sponsored by the NASA Environmental Management Office, will evaluate the capability of flywheel-based UPS systems to provide a cleaner, safer, long life, lower cost alternative to the lead acid batteries currently in use at NASA.

“We are very pleased to be selected by NASA and are looking forward to providing our solution to meet the Glenn Research Center’s power quality and reliability needs.” said Paul Craig, CEO of Pentadyne.

Pentadyne’s flywheel system provides a stable, reliable, low maintenance, extended-life DC voltage source to either replace or supplement batteries in UPS systems. The VSS 120 can completely eliminate the need for UPS batteries in many applications by providing sufficient ride-through for an orderly system shutdown or until a standby engine-generator can come on-line.

To help protect batteries, the Model VSS 120 minimizes battery discharge “whiplash” effects commonly experienced with each use, thus improving battery reliability and preserving battery capacity for occasions that demand a longer back-up time. The Model VSS 120 delivers 2,400 kilowatt-seconds of energy, sufficient to support loads ranging from 120 kW for 20 seconds to 10 kVA for about 5 minutes.
