20C1000 Series Cable / Telecom Flywheel System  
Beacon Power Corporation
234 Ballardvale Street Wilmington, MA 01887  
 
Description 
 The Flywheel Energy Storage System (FESS) will provide standby power for
telecommunication and cable TV networks. The FESS consists of a flywheel
module and electronics module, and is designed to act as an energy
reservoir to provide a stable supply of power, either when utility power
lines are interrupted, or when voltage level falls below acceptable levels.

Hold up Time 
 4 hours at 500W 
(>4 hours for continuous electrical power < 500W) 
 
 
Output Energy—Usable 
 2 kWHr 
 
 
Output Voltage 
 36, 48, or 96 VDC nominal 
 
 
Input Voltage 
 120/240 VAC, 50/60 Hz 
 
 
Input Power 
 4 kW max 
 
 
Discharge Mode 
 Automatic upon loss of utility power 
 
 
Recharge Mode 
 Automatic switch back to recharge 
 
 
Charge Time 
 Less than 3 hours from full stop 
 
 
Recharge Time 
 2 hours or less recharge to full capacity 
 
 
Dynamic Response 
 33 VDC to 42 VDC (36V); 44 VDC to 56 VDC (48V); 88 VDC to 112 VDC (96V) 
 
 
Recharge Input Power 
 2.5 kW Maximum 
 
 
Size—Flywheel Module 
 36" high x 27" diameter 
 
 
Size—Electronics Module 
 32" high x 18" wide x 12" deep 
 
 
Weight—Flywheel Module 
 850 lbs 
 
 
Weight—Electronics Module 
 200 lbs 
 
 
MTBF 
 100,000 Hours 
 
 
Design Life 
 20 years (maintenance free) 
 
 
Operating Ambient Temperature 
 -40ºF (-40ºC) to 150ºF (65ºC) 
 
 
Acoustical Noise 
 < 55 dBA at 6 ft. (when installed in the ground) 
 
 
Environmentally Induced Vibration 
 Meets Bellcore specification TA-NWT-000487, Section 4.19 
 
 
Earthquake 
 Meets Bellcore specification GR-63-CORE, Section 4.4.1, Zones 1&2 
 
 
Immersion 
 Flywheel module is capable of full immersion 
 
 
Internal System Protection 
 The FESS has an internal safety system protection which will shut-down the
unit if one of the following parameters exceeds predetermined limits:

Speed 
Vibration 
Power in Float Mode 
Output Voltage 
Motor Temperature 
Bearing Temperature 
Electronics Temperature
