W650 Wind Generator Protection System

The modular W650 unit has been designed as a comprehensive generator controller specially adapted to wind turbine generators.
Based on the state of the art W650 family, it utilizes modern 32 bit processor platform to provide a complete solution not only for
the needs of present systems but also ready for the future.
The W650 simplifies the design of systems in wind turbine generation due to the complete set of protection, measurement,
control and recording functions. Maintenance is eased thanks to the modular design whereas cost is scalable depending on the
options to allow a cost effective solution from medium to large size generators.
