San Diego, Calif. — Boosting its expansion in the growing wind energy industry, Maxwell Technologies Inc. has announced that LTi REEnergy GmbH (LTi), a producer of electromechanical wind turbine blade pitch control systems, has selected Maxwell's BOOSTCAP ultracapacitors to supply backup power for LTi's PitchMaster blade pitch control system.
The LTi PitchMaster system will incorporate multi-cell BOOSTCAP ultracapacitor modules based on Maxwell's BCAP0350 "D cell" product. The ultracapacitors supply backup power for orderly system shutdown in the event of a main system power failure.

LTi chose the ultracapacitors over batteries for backup power for several reasons: longer operating life, lower maintenance requirements and higher reliability operation in harsh climates. The company said the BOOSTCAP products have demonstrated reliability over the temperature range of -40°C to 65°C.
