Operation Manual

BASLER AVC63-4 ANALOG VOLTAGE CONTROLLER
The AVC63-4 voltage regulator is designed for use on 50/60 Hz brushless generators. Features
include frequency compensation, over excitation shutdown, a solid-state build-up circuit and EMI
filtering. The AVC63-4 attaches to the generator with spade type wire terminals for a secure connection.
The AVC63-4 has three adjustable potentiometers for fine-tuning the output voltage, stability and under
frequency. The regulator is encapsulated in a protective plastic shell and back filled with an electronic
compound, which provides protection from environmental hazards.
