Chatsworth, Calif. - July 19, 2005-Pentadyne Power Corporation today announced that it has entered into a distribution agreement with Ehwa Technologies Information (ETI), the largest uninterruptible power supply (UPS) manufacturer in South Korea. Under the terms of the agreement, ETI will now make available the Pentadyne Voltage Support Solution™ (VSS 120) with many of its UPS models. Pentadyne's flywheel power 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. When used in combination with batteries, the 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. When connected to most UPS models, a single model VSS 120 provides sufficient energy to support loads up to 225 kVA, depending on the back-up time required. Multiple VSS units in parallel provide economic ride-through for power levels up to 2 MW.

Frank DeLatttre, Pentadyne's senior vice president sales said, "ETI's 60% share of the Korean domestic UPS market opens an exciting new channel for the adoption of Pentadyne's advanced flywheel energy technology. The quality and reliability of the VSS 120 makes it an excellent complement to the ETI UPS product line. ETI has a long and accomplished history of providing quality power products to customers world wide and we are eager to launch our new partnership with ETI."

According to Wook Dong Kim, CEO of ETI, "Our mission is to meet customers' requirements and expectations by developing continuously innovative technology and solutions. The environmental friendly, low-maintenance benefits of the Pentadyne VSS 120 meet these criteria perfectly. Our customer base has been seeking alternatives to lead acid based energy storage and our partnership with Pentadyne will allow us offer them a reliable, cost-effective solution. Our extensive UPS product lines, including the high-performance ETUS line and the environmentally sensitive Green UPS line, are ideal candidates for this advanced flywheel energy storage system."
