The DC900C series governor is composed of the relevant control elements and is provided to the user after being packaged in a suitable housing. The device inputs standard three-phase alternating current ranging from 110V to 500V. Suitable for controlling separately excited DC motors or permanent magnet DC motors, providing adjustable DC voltage and current for armature and excitation windings. The unit is designed with mounting holes for simple and economical cabinet installation, and pluggable connectors facilitate the installation and removal of components. The control loop is completely isolated from the power loop, which simplifies the connection between the controllers in the system and improves operator safety. The input circuit ADAPTS to the power grid frequency changes between 45-65Hz, and it has a strong immunity to interference from the power grid.
