Marathon Electric AVR DVR2000E
The DVR2000E is an electronic, solid-state, microprocessor-based control device.
It has many advantages:
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.
• Underfrequency (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.
