DVR2000E - Marathon

EXPORT ONLYTheMarathon DVR®2000Evoltage regulatoris an electronic, solid state, microprocessor-based control device. The Automatic Voltage Regulator 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).Marathon DVR2000E Voltage Regulator Features and Capabilities:Four control modes:Automatic Voltage Regulation (AVR)Manual or Field Current Regulation (FCR)Power Factor Regulation (PF)Reactive Power Regulation (VAR)Programmable stability settingsSoft start control with an adjustable time setting in AVR control modeOverexcitation limiting (OEL) in AVR, VAR and PF control modesUnderfrequency (volts/hertz) regulationCrowbar circuitry protects the fieldOvertemperature protectionThree-phase or single-phase generator voltage (RMS) sensing/regulation in AVR modeSingle-phase generator current sensing for metering and regulation purposesField current and voltage sensingFour contact sensing inputs for system interfaceOne common output relay for alarm indication and trip functionsSix protection functionsOverexcitation shutdownGenerator overvoltage shutdownDVR overtemperature shutdownLoss of generator sensing shutdownOverexcitation limitingCrowbar shutdownGenerator paralleling with reactive droop compensation and reactive differential compensationFront-panel human-machine interface (HMI) indicates system and DVR2000E status and gives the ability to make setting changes at the front panelRear RS-232 communication port for personal computer communication using MARATHON-DVR2000E-COMS Windows-based software for fast, user-friendly setup and controlMarathon DVR2000E Voltage Regulator Product DescriptionTrue RMS Sensing ± One or Three PhaseConnect the sensing mode you prefer.Senses 95 to 600 volts ±10% at 50/60 hertz.Patented circuitry senses true RMS voltage rather than average for superior load regulation.Soft-Start Ramp o
