The ultracapacitor system from DEIF Wind Power Technology consist of two building blocks: an UCC-4 Ultra Cap Charger and an UCM-90 Ultra Cap Module. The system is modular, supplying a voltage of 90VDC/4A, and can be configured parallel or serial up to a system voltage of 450 VDC.

The ultracapacitor system features full self-contained condition monitoring and has outputs for communication of alarms. In terms of ESD protection and long term tolerance towards mechanical stress, the system is constructed to cope with the real-life demands of operation in the rotating hub of the wind turbine.

As no explosive gasses evaporate from the ultra caps, they can be mounted inside the pitch panel. Space requirement is kept at a minimum, allowing for design of very compact pitch panels.

The lifetime of ultra caps is 10+ years and will over the lifetime of a wind turbine be a more economical choice than conventional batteries due to considerably longer service intervals. This also makes ultracapacitor technology far more environment-friendly than conventional batteries.
