One DECS-200 Digital Excitation Control System can accommodate 32Vdc, 63Vdc, or 125Vdc applications up to 15Adc. This unique flexibility provides precision control of virtually any size generators. The DECS-200 also incorporates a pulse width modulated power stage, which improves system performances in non-linear load applications.
The microprocessor-based DECS-300 provides precision control for generators of virtually any size and is equally suited for exciter field or main field applications. It provides control signals for pulse width modulated power modules and SCR bridges manufactured by Basler Electric and other manufacturers.
The DECS-400 is a microprocessor-based controller that provides excitation control, flexible logic control, and optional power system stabilization for synchronous machines in an integrated package. The controller provides an analog output to control the firing of external bridge(s) and monitors machine parameters to control, limit, and protect the synchronous machine from operating beyond its capability limitations.
