XD2S DC

Compact device for excitation of synchronous machines with an integrated power circuit

Überblick

The XD2S DC devices are equipped with an integrated power circuit for up to 30 A.

Applications include the excitation and monitoring of brushless synchronous machines as well as excitation-machine-equipped synchronous machines.

The XD2S family is a system of compact devices for synchronous machine excitation with two basic configurations. The devices can be either integrated with the power circuit or control/drive an external circuit for excitation and monitoring of machines in the range of hundreds of megawatts, and can also be used for smaller units of a megawatt or less.
