GENERAL

The Marathon AVR DVR2000E+ is a microprocessor-based control device that regulates the output voltage of a brushless, ac generator by controllingthe current into the generator exciter

field. Input power to the DVR2000E+ is derived from a single phase, multi-pole, highfrequency, permanent magnet generator (PMG).

The Marathon DVR2000E+ Automatic Voltage Regulator is supplied in an encapsulated package designed for behind-thepanel mounting. The DVR2000E+ Marathon AVR is held in place by thread-forming screws that thread into its plastic shell. The front panel display annunciates regulator status and system conditions. DVR2000E+ Marathon Automatic Voltage Regulator connections are made through four types of connectors:

•  Ten quarter-inch, quick-connect terminals for generator connections

•  Two 12-pin Deutsch (DTC style) connectors for current transformer (CT) and system interface connections

•  One 3-pin Amp/Tyco Mini Mate-N-Lok receptacle for CAN bus interface.

•  One 9-pin DB-9 type connector for communication between the DVR®2000E+ and a Windows® compatible PC.

AVR DVR2000E+ has the following features:

•  Three regulation modes: single phase automatic voltage regulation (AVR1), three phase automatic voltage regulation (AVR3) and fieldcurrent regulation (FCR)

•  Preset stability settings

•  Adjustable soft start in AVR1 or AVR3 regulation modes

•  Under frequency (volts/hertz) regulation

•  Three-phase or single-phase generator voltage (RMS)sensing

•  Three-phase or single-phase generator current (RMS)sensing

•  True three-phase power metering

•  Field current sensing

•  Field voltage monitoring

•  Contact inputs for system interface capability

•  Contact output for fault indication

•  Generator paralleling with reactive droop compensation and reactive differential

compensation

•  Front-panel human-machine interface (HMI) for status and configuration

•  MODBUS protocol via RS232 for external communication

•  DVR2000E+ Windows® based software for configuration and monitoring

•  Controller Area Network (CAN) interface with CAN 2.0B J1939 protocol for

metering and control

•  “Power on” LED indicator

•  Configurable auxiliary input for metering and control
