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
