Unitrol 6080 Automatic Voltage Regulator

UNITROL 6000 is ABB’s latest generation of Automatic Voltage Regulators (AVR) and Static Excitation Systems (SES). Its smaller version UNITROL 6080 is a compact and cost efficient solution. The proven pre-engineered building blocks ensure continuous high quality combined with short delivery times.

UNITROL 6080 AVRs application range

  • UNITROL 6080 AVR systems are PowerPC®-based (64 bit floating point CPU) voltage regulators from small to large synchronous generators / motors equipped with exciter machines.
  • 50…480 Hz AC source supplied Automatic Voltage Regulator (AVR) family for exciter machines with field currents up to 400 ADC at up to 500 VAC supply voltage
  • Single-phase supply up to rated field currents of 60 ADC with full wave controlled single-phase (2 pulse) thyristor bridge
  • 3-phase supply up to rated field currents of 400 ADC with fully controlled 3-phase (6 pulse) thyristor bridge

UNITROL 6080 AVRs are fully configurable in terms of:

  • Redundancy (single / double channel control configuration; additional back-up controller on request) including on-line maintenance
  • Supply scheme
  • Control sequence, channel transfer and monitoring options
