Specification:
The AVR is linked with the main stator windings and the exciter field windings to provide closed loop control of the output voltage with load regulation of +/- 1.0%.
Over excitation conditions are limited to a safe period by a protection circuit within the AVR.
Provision is made for the connection of a remote voltage trimmer, allowing the user fine control of the generator's output.
An analogue input is provided allowing connection to a Newage Power Factor controller or other external devices with compatible output.
The AVR has the facility for droop CT connection, to allow parallel running with other similarly equipped generators.
Description:
High quality and durable
Good working conditions and easy installation
Sufficient warranty time and good after-sales service
