CHATSWORTH, CA¬ -Pentadyne Power Corporation announced on August 6th that one of its flywheels is now part of the power protection system for KDEN-DT’s digital television transmission facility near Denver. The Pentadyne system is operating as the sole source of energy storage for the transmission site’s uninterruptible power supply (UPS) system. Dirk Freeman, president of Blair Media Inc., which develops and manages digital broadcast properties, chose a Pentadyne flywheel and a 225-kVA Toshiba G8000 UPS system to ensure continuous operation of the DCX Paragon MSDC-IOT at KDEN’s multi-million-dollar digital transmission site. “Over the years, we’ve been made painfully aware of the short-comings of UPS batteries. That’s why we chose to eliminate those problems and their costs with this battery-free solution that began operating two weeks ago,” Freeman said.
