BASLER MODEL AVC63-4 VOLTAGE REGULATOR
Control is different on previous versions of the AVC63-4. When adjusting the Underfrequency Control
on previous versions, clockwise rotation decreased the corner frequency while counterclockwise
increased the corner frequency.
NOTE: Further reference to corner frequency adjustments of the AVC63-4 are for the Current Version
and should be reversed for the Previous Version.
JUMPER CONTROLS:
Two jumpers connect to the controller
terminals: the Corner Frequency Jumper
and the Voltage Adjust Rheostat Jumper.
Corner Frequency Jumper
The AVC63-4 is typically set with this
jumper connected to the 60 Hz terminal.
This gives a corner frequency of 55 Hz.
For 50 Hz operation and a corner
frequency of 45 Hz, the Corner Frequency
Jumper must be moved to the 50 Hz
terminal.
Voltage Adjust Rheostat Jumper
The Avc63-4 is typically set with the
Voltage Adjust Rheostat Jumper connected
across terminals 6 and 7. This enables
adjustment of the generator output voltage
through the controller's internal voltage
control potentiometer. Clockwise rotation
of the voltage control increases generator
voltage.
POTENTIOMETER CONTROLS:
The AVC63-4 potentiometer controls are located on the components and terminals side of the controller.
Voltage control, Stability control and Underfrequency control allow for fine-tuning the controller to a
specific application.
INPUT POWER / SENSING INPUT:
Power for the exciter field and AVC63-4 is derived from the generator output. The acceptable power
input range is 171 to 264 V AC and is connected to terminals 3 and 4.
EXCITER FIELD POWER CIRCUIT:
Controller terminal F+ is connected to the brushless exciter field positive terminal and controller
terminal F- is connected to the brushless exciter field negative terminal.
