ULTRA3000 Pitch Energy Module – Patented Technology

ULTRA3000 Pitch Energy Module – Patented Technology

Ultracapacitor-based energy storage solutions have significantly enhanced reliability in electric pitch control systems. Ultracapacitors, unlike batteries, have the ability to deliver quick bursts of power in a short time frame, an ideal function for emergency pitching in a wind turbine generator (WTG).

The ULTRA3000® Pitch Energy Modules (Patented Technology) is a direct one-to-one replacement for the GE* batteries and chargers and can be installed with no modifications to the battery box. Our Pitch Energy Module (PEM) communicates directly with the GE controller and reports all necessary diagnostic information back to the controller.

We have designed our PEM with owners and installers alike in mind, by eliminating the need for modifications of the wiring harness, installation of additional brackets, or the need to relocate existing components. This greatly reduces installation time, reduces labor costs, and decreases downtime. With over 1 million charge-discharge cycles, our Ultracapacitor Pitch Energy Modules can provide 15 plus years of reliable operation without maintenance.
