BASLER DECS-200-2L Digital Excitation Control System DECS2002L
BASLER DECS-200-2L Digital Excitation Control System DECS2002L
One DECS-200 Digital Excitation Control System can accommodate 32Vdc, 63Vdc, or
125Vdc applications up to 15Adc. This unique flexibility provides precision control of
generators of virtually any size. The DECS-200 also incorporates a pulse width modulated
power stage, which improves system performances in non-linear load applications.
