THE HEART OF YOUR SYSTEM

The DECS-200 is an excitation control system used to control the output voltage, vars or power factor of a synchronous generator by varying or controlling the amount of DC excitation applied to the generator’s exciter field. Suitable for virtually any size machine, the microprocessor-based DECS-200 is a total excitation control system in one enclosure. It contains all the functionality necessary to control, limit, and protect a generator from operating outside of the machine’s capability.
