The DSR is a full digital controlled regulator based on DSP (Digital Signal Processor) that combines function as Voltage Regulation and Alternator Protections and Diagnostic into a very small single board. Digital communication interface DI1 allows the connection of the DSR digital regulator to a programming and monitoring device, as a PC or PLC. IF321 optional interface allows a three phases sensing on the generator. "DSR Terminal" software, user friendly graphical interface (windowsbased), designed by Mecc Alte. allows users to work with settings and alarms on the DSR via their personal computer.
