Marathon Electric Digital Voltage Regulator AVR DVR2000E Easy Operation Manual

GENERAL
The DVR®2000E+ is a microprocessor-based 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 DVR®2000E+ is derived from a single phase, multi-pole, high-frequency, permanent magnet generator (PMG).
The DVR®2000E+ is supplied in an encapsulated package designed for behind-the-panel mounting. The DVR®2000E+ is held in place by thread-forming screws that thread into its plastic shell. The front panel display annunciates regulator status and system conditions. DVR®2000E+ 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.

FEATURES
DVR®2000E+ has the following features:
• Three regulation modes: single phase automatic voltage regulation (AVR1), three phase
automatic voltage regulation (AVR3) and field current 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
• DVR®2000E+ 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
