SAN DIEGO--Maxwell Technologies, Inc. (Nasdaq: MXWL) announced today that Dantherm Power A/S, a leading developer of hydrogen and fuel cell-based power supply solutions, has selected Maxwell's BOOSTCAP(R) ultracapacitors as the short-duration "bridge power" element of its integrated uninterruptible power supply (UPS) systems for telecommunications and fiber broadband applications.

David Schramm, Maxwell's President and Chief Executive Officer, said that Dantherm Power, based in Skive, Denmark, has signed a strategic supply agreement through which it will source ultracapacitors exclusively from Maxwell, and has placed an initial purchase order through Alphatron Electronic Parts B.V., Maxwell's business partner for Denmark, Belgium, Luxembourg and the Netherlands.

Per Albaek, Dantherm Power's President and Chief Executive Officer said that the systems use ultracapacitors to instantaneously (0 msec) buffer protected loads from short-duration power disturbances and, in the event of a longer power outage, to supply bridging power for fuel cell backup power to reach its nominal capacity.

"In tandem with fuel cells, ultracapacitors enable our systems to meet our customers' toughest requirements and offer a number of advantages over batteries," Albaek said. "Ultracapacitors have much longer operational life, require little or no maintenance and are far more reliable, especially in harsh environments where backup power often is needed most. The use of ultracapacitors also reduces the overall system weight and volume due to the stable capacity in farads that enables us to scale the bridge power to the exact system requirements."

"The Dantherm Power UPS solution is an excellent example of how ultracapacitors can be used to enhance the reliability and efficiency of systems that generate or consume energy," Schramm said. "We are pleased to be aligned with one of the industry's leading power systems innovators."
