Digital Voltage Regulator DVR2400

This manual provides details on how to install, operate and maintain
a DVR®2400 or DVR®2500 digital voltage regulator with Marathon®
synchronous generators. A separate publication is available for Controller
Area Network (CAN) communications.
The regulator is a control device that regulates the output voltage of a
brushless, AC generator by controlling the current into the generator
exciter field. Input power to the regulator is derived from a single phase
permanent magnet generator (PMG).
The regulator is supplied in an encapsulated package designed for
behind-the-panel mounting. It is held in place by thread-forming screws
that thread into mounting holes in the face of the regulator. The front
panel display annunciates regulator status and system conditions.
