Marathon DVR2000 E+

Replaces Marathon DVR2000 voltage regulator (out of production).

The DVR2000E is an electronic, solid state, microprocessor-based control device. The DVR2000E regulates the output of brushless, AC generators by controlling the current into the generator exciter field. Input power to the DVR2000E is a multi-pole, high frequency, permanent magnet generator (PMG).

REGULATION MODES
Three regulation modes:
• Single phase automatic voltage regulation (AVR1) • Three phase automatic voltage regulation (AVR3)
• Field current regulation (FCR). The DVR®2000EC+ adds two regulation modes:
• Reactive power regulation (VAR) • Power factor regulation (PF
