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.

Previous Version Current Version
Previous versions of the AVC63-4 controller, sold prior to mid-2003, are slightly different in appearance
and control adjustment. The controller version can be determined by the location of the heat sinks. The
above illustrations show the heat sink locations of both versions. Adjustment of the Under frequency
