Chatsworth, Calif. - October 25, 2005 - Pentadyne announces the VSSDC+ - the next generation of its advanced Voltage Support Solution (VSS DC) flywheel power system-designed to improve overall Uninterruptible Power Supply (UPS) systems reliability by completely replacing or greatly extending the life of lead-acid batteries. The VSS DC+ provides increased high-power performance added to the high reliability, low maintenance and a long useful life that characterized its predecessor the VSS DC. Additionally, the VSS DC+ provides significant cost savings in parallel system applications up to 1000 kVA and beyond. For instance, only four VSS DC+ units are required to supply back-up power to a 750 kVA UPS for 17 seconds. Target markets for the Pentadyne VSS DC+ include the full spectrum of companies serving the digital economy, industrial plants, healthcare buildings, broadcast facilities and other commercial structures.

• Ride-through Protection-integrated with a UPS, the VSS DC+ provides sufficient ride-through for a safe system shutdown of most process operations. A single VSS DC+, for example, can provide 13 seconds of ride-through for a 225 kVA UPS at 100% output, more than ample time for 99.5% of power disturbances which are only a few cycles to a few seconds duration.
  
  
• Ride-through to Generator-the VSS DC+ provides sufficient ride-through until a standby engine-generator can come on-line to protect against long-term grid outages.
  
  
• Battery-life Extension-in parallel with UPS batteries, the VSS DC+ handles short-duration power disturbances, thus preserving battery capacity for longer events and extending battery life, reducing life-cycle costs while improving UPS reliability.
  
  
• The VSS DC+ integrates indifferently with medium and large power UPS systems. At 100% UPS output power, a single VSS DC+ unit provides up to 25 seconds in a 130 kVA UPS and 40 seconds in a 80 kVA UPS. For large power UPS systems, as many VSS DC+ systems as desired can be paralleled together for higher power, longer run-time or redundancy without requiring any communication links.
Key VSS DC+ system features include:Five-Year Warranty Vs. the Industry's Standard One-Year Warranty
No Bearing Maintenance nor Replacement Required
No Vacuum Pump Maintenance nor Replacement Required
High Efficiency-greater than 99.8%, typical
Quiet Operation-45dBA @ 1m
Easy InstallationDesigned for a 20-year service life before major service is required, the compact, self-contained VSS DC+ weighs around 1300 lbs (590kg) and is housed in a steel cabinet that can be rolled into place and that occupies less than six square feet of floor space. The VSS DC+ requires no air conditioning or safety systems; contrary to lead-acid batteries. The VSS DC+ is the flywheel power system that provides the best value for customers with critical applications in need of reliable power.
