Powerful controllers that offers reliable operation and proven performance.

Drawing upon a legacy of expertise in wind turbine controller innovation, our cutting-edge controllers serve as the central control hub for wind turbines and other renewable energy applications.

Cutting-edge controllers

We provide robust controllers known for their dependable operation and established track record of high performance.

Our time-tested controller platforms deliver exceptional performance and are meticulously engineered to endure the challenging environmental conditions, both onshore and offshore. 

Main controller

A powerful main controller that combines long lifetime and stable operation with industry-leading connectivity.



I/O controller

Combining many features in one board, IO60 helps keep cost and complexity to a minimum. The status of all inputs and outputs is available via the EtherCAT network interface and visible on the board. 



String controller

A robust battery controller designed to efficiently manage power in energy storage systems.

MC60 String controller


Legacy WTC3 controllers

With thousands of modules in operation at sites both on- and offshore, our legacy controllers have proven the test of time.

WTC3 Main controller

WTC3 Main controller, with dedicated design for operation in wind turbines both on- and offshore. 

WTC3 Hub module

WTC3 Hub Module ensures reliable control of the pitch position in wind turbines, contributing to lowering O&M costs for your wind power plant.

WTC3 Grid module

Reliable grid monitoring module to supports safe and reliable operation of wind turbines with or without voltage transformers.

Pioneering control technology


The company founders, Kai F. Pedersen and Knud V. Jensen, built one of the world’s first electrical control systems for a wind turbine, the Riisager 22kW turbine.


We continue to develop early control systems for wind turbines. It is installed in a 50kW Windmatic.


We launch the industry’s first SCADA system for turbine monitoring, improving access to data on turbine condition and performance.


We partner with Bonus Energy (later to become Siemens Gamesa), becoming its sole supplier of control systems.


The first offshore wind farm in the world is built at Vindeby, Denmark, equipped with our control and surveillance systems. 


A new control system for wind turbines, WTC3, is launched and becomes our key product in the following years.


We launch the new WTC6 controller and start retrofitting control systems in Vestas and Siemens Gamesa turbines.


The MC60 string controller is launched and used alongside the WTC6 controller in a variety of energy subsystems


Leveraging our proficiency in turbine controls, we venture into the Power-to-X (PtX) and form new partnerships.
