240V Ultracapacitor Module

Customers in the wind industry leverage this cost-effective solution as a backup power supply to the wind turbine’s emergency pitch control system. The modules require minimal to no maintenance, withstand the wind turbine’s aggressive environment, and contribute to streamlined wind farm operations.

The 240-volt Ultracapacitor module offers:

  • fast-responding
  • high power energy storage with the advantages of low internal resistance
  • passive cell balancing
  • a wide operating temperature range of –40°C to 65°C
  • up to 500,000 duty cycles or 10-year life,
  • ensuring long-lasting
  • reliable performance in your system

In addition, the 240-volt module is deployed as bridge power for large-scale industrial uninterruptible power supply (UPS) in data centers, hospitals and high-tech manufacturing, and can be customized for 20 kW to multi-megawatt systems. The 240-volt solution streamlines the transition to the backup energy source by bridging the energy gap with several seconds of reliable power. Maxwell’s Ultracapacitor solution outperforms most battery technologies for industrial UPS, an application in which lead-acid batteries often suffer from short lifetimes and unexpected failures. The durability of Maxwell’s proprietary Ultracapacitor cell technology achieves significantly longer lifetime and high reliability due to the electrostatic mechanism for storing energy.
