Digital excitation control system DECS-200

One DECS-200 Digital Excitation Control System can accommodate 32Vdc, 63Vdc, or 125Vdc applications up to 15Adc. This unique flexibility provides precision control ofgenerators of virtually any size. The DECS-200 also incorporates a pulse width modulatedpower stage, which improves system performances in non-linear load applications.
