AVR DVR2000E DAVR2000E DIGITAL REGULATOR DVR 2000E DVR-2000E DAVR 2000E
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 field. Input power to the DVR2000E is from a multi-pole, high-frequency, permanent magnet generator (PMG)
FEATURES
DVR2000E units have the following features and capabilities
Four control modes: automatic voltage regulation (AVR), manual or field 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
Overexcitation (OEL) limiting in AVR, VAR, and PF control modes
Under frequency (volts/hertz) regulation
Crowbar circuitry protects the field
Overtemperature protection
Three-phase or single-phase generator voltage (RMS) sensing/regulation in AVR mode
Single-phase generator current sensing for metering and regulation purposes
Field current and field voltage sensing
Four contact sensing inputs for system interface
One common output relay for alarm indication and trip functions
Six protection functions (overexcitation shutdown, generator overvoltage shutdown, DVR overtemperature shutdown, loss of generator sensing shutdown, overexcitation 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
Rear RS-232 communication port for personal computer communication using MARATHON-DVR2000E- COMS Windows based software for fast, user-friendly, setup and control
