DECS-200N Negative Forcing
Digital Excitation Control System

The DECS-200N is a very compact Negative Forcing Digital Excitation Control System.

This multiple microprocessor-based design accommodates 63 Vdc and 125 Vdc applications up to 20 Adc continuously. The on-board six-thyristor controlled rectifier bridge offers the highest system performance possible, making the DECS-200N ideal for providing exceptional system response, which makes it suitable for applications requiring power system stabilizers.
