Generator Control Units

Generator Control Unit

Patented Technology

We have decades of experience in developing and manufacturing Starter Generators and Generator Control Units (GCU) and have become the aerospace industry leaders in size, weight, power output and reliability.

Our versatile GCU's are available as COTS or can be tailored for your exact specifications, including single or twin-engine system designs. Each unit is designed to provide exceptional voltage regulation, fault protection and soft start features. In addition, our patented technology solution delivers proprietary soft charging for enhanced battery life.  

These key features have enabled us the opportunity to produce numerous analog and digital generator control units each customized for the individual customers’ needs.
