ULTRA3000 Pitch Energy Module – Patented Technology

The Richardson Electronics ULTRA3000®  Pitch Energy Module (PEM) is an ultracapacitor-based plug and play replacement for batteries within GE wind turbine pitch systems and is compatible with all General Electric (GE)* 20 & 30 Nm pitch systems.

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® PEM is a direct one-for-one replacement for the GE Batteries and chargers and can be installed with no modifications to the battery box. Our PEM communicates directly with the GE controller and reports all necessary diagnostics.

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, reducing labor costs, and decreasing downtime.

With over 1 million charge-discharge cycles, our Ultracapacitor Pitch Energy Modules can provide 15 plus years of reliable operation without maintenance.
