AVR DVR2000E+ Automatic Voltage Regulator AVR Voltage Regulator Genset Accessory

AVR DVR2000E+ Automatic Voltage Regulator AVR Voltage Regulator Genset Accessory

Description:
AVR DVR2000E+ is an electronic, solid-state, microprocessor-based control device. The DVR2000E+ regulates the output voltage of a brushless, ac generator by controlling the current into the generator exciter. Input power to the DVR2000E+ is from a multi-pole, high-frequency, permanent magnet generator (PMG).

DVR2000E+ is supplied in an encapsulated package designed for behind-the-panel mounting. The DVR2000E+ is held in place by thread-forming screws that thread into its plastic shell. Front panel indicators (LEDs) annunciate regulator status and system conditions. DVR2000E+ connections are made through quarter-inch, quick-connect terminals on the rear panel. A 9-pin DB-9 type connector on the rear panel provides communication between the DVR2000E+ and an IBM compatible PC.

Features:
- Four control modes: automatic voltage regulation (AVR), manual or current regulation (FCR), power factor (PF) regulation, and reactive power (VAR) regulation.
- Programmable stability settings.
- Soft start control with an adjustable time setting in AVR control mode.
- Over-excitation (OEL) limiting in AVR, VAR, and PF control modes.
- Under-frequency (volts/hertz) regulation.
- Crowbar circuitry protects the area.
- Over-temperature protection.
- Three-phase or single-phase generator voltage (RMS) sensing/regulation in AVR mode.
- Single-phase generator current sensing for metering and regulation purposes.
- Current and voltage sensing.
- Four contact sensing inputs for system interface.
- One common output relay for alarm indication and trip functions.
- Six protection functions (over-excitation shutdown, generator over-voltage shutdown, DVR over-temperature shutdown, loss of generator sensing shutdown, over-excitation limiting and crowbar shutdown).
- Generator paralleling with reactive droop compensation and reactive differential compensation.
- Front-panel human-machine interface (HMI) indicates system and DVR2000E+ status and gives the ability to make setting changes at the front panel.
