75 Volt Power Module
ASK Technologies’ 75V module is designed for low duty cycle energy storage applications such as wind turbine pitch control and backup power generation systems. The module includes passive balancing circuitry and thermal monitoring, and its enclosure meets the IP54 standard.
The standard monitoring and mechanical interfaces enable quick integration into existing infrastructures and remote monitoring systems. The module delivers the long lifetime -- up to 17 years (at 25° C) -- characteristic of ASK ultracapacitors. This means virtually maintenance free operation throughout the entire lifecycle of a wind turbine.
