Pentadyne Intros VSS-120 Voltage Support Flywheel
Pentadyne Power Corp. (Chatsworth, CA), developer of flywheel power systems for power quality, distributed power and power recycling applications, announced its new Pentadyne Voltage Support Solution™ flywheel power system, which provides a stable, reliable, low-maintenance, extended-life, dc voltage source to condition or completely replace batteries in UPS systems.
As a battery conditioner, the Model VSS-120 minimizes the battery discharge "whiplash" effects commonly experienced with each use, improving battery reliability and preserving battery capacity for occasions that demand a longer backup time. In addition, 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.
The Model VSS-120 delivers 2,400kW-sec of energy, sufficient to support loads ranging from 120kW for 20sec to 10kVA for 5min. The compact, self-contained Pentadyne Voltage Support Solution is housed in a cabinet requiring about 6ft² of floor space and weighing around 1,000lbs. In contrast to batteries, the VSS-120 requires no special environmental control and operates over -20°C to +80°C. Unlike battery systems, the VSS-120 can be recharged at the same rate as it discharges; and once fully charged, it requires just 120W for standby operation. The system is designed for a 15-year life before any major service is required.
Availability is for first-quarter 2004 (units will be available in second-quarter 2003 at higher prices). Delivery is 12 to 16 weeks, ARO.
