OVERVIEW
DVR2400 DVR2500
The digital voltage 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 digital voltage regulator is
derived from a single phase permanent magnet generator (PMG).
The digital voltage regulator is supplied in an encapsulated package
designed for behind-the-panel mounting. It is held in place by threadforming screws that thread into mounting holes in the face of the digital
voltage regulator. The front panel display annunciates regulator status and
system conditions.
REGULATION MODES
Five regulation modes:
Single phase automatic voltage regulation (AVR1)
Three phase automatic voltage regulation (AVR3)
Field current regulation (FCR)
Reactive power regulation (VAR)
Power factor regulation (PF)
