AVR DECS-150
DECS-150 Digital Excitation Control Systems offer precise excitation control and machine protection in a compact package. The DECS-150 is suitable for the Mecc Alte brushless alternators start from ECO38 to ECO46, included the medium and high voltage series ECO46 and ECO49. In fact, the DECS-150 can be fed indifferently by the PMG3, MAUX or even shunt-excited.
DECS-150 Digital Excitation Control Systems offer precise excitation control and machine protection in a compact package. DECS-150 adaptability to many applications is assured through configurable contact inputs and outputs, flexible communication capabilities, and programmable logic implemented with the provided software. The high flexibility and powerful functionalities makes this device particularly useful in those projects where machines are paralleled to other generators and/or the utility system, since the requirements from the grid codes are very demanding.
