Description

  • The AVR includes an over-voltage protection feature with internal shutdown of the AVR output device, plus the ability to trip an optional excitation circuit breaker if required.

  • Adjustable Soft start circuit is included to provide a smooth controlled build up of generator output voltage.

  • The AVR has the option for droop CT connection, to allow parallel running with other similarly equipped generators.

  • An analogue input is provided allowing connection to a New Age Power Factor controller or other external device with compatible output.
