The AVR-8 voltage regulator is an electronic device which lets the alternator to produce a fixed output voltage.
The device has open chassis, resin molded design. It is intended to be mounted in the alternator’s terminal box. The unit does not include moving parts; therefore it is able to operate in highly vibrating environments.
The device measures phase-to-neutral or phase-to-phase voltage of the alternator and adjusts the DC voltage applied to the excitation winding until reaching the desired voltage. The unit offers low-frequency protection feature. A frequency measuring circuit continually monitors the generator output and provides output for low-frequency protection of the excitation system, by reducing the output voltage proportionally with frequency below a manually adjustable threshold. The nominal frequency can easily be changed to 50 or 60Hz in the field by push-on link selection.
Features:
Universal operation
Half-Wave thyristor output
Designed for highly vibrating environments
Built-in voltage adjustment
Stability adjustment
Compatible with various types of alternators
External trimmer voltage adjustment input
