BASLER ELECTRIC, BOX 269,
INTRODUCTION
The AVC63-2.5 Voltage Regulators
designed for use on 50/60 Hz brushless
generators. The regulator includes frequency
compensation, a solid-state build-up circuit,
EMI filtering, and remote adjust capability.
Warning
To prevent personal injury or equipment
damage, only qualified technicians or
operators should install, operate, or
service this device.

V/HZ "CORNER FREQUENCY" SELECTION
AND ADJUSTMENT
The corner frequency can be adjusted by the
UF ADJ rheostat on the AVR. Clockwise
rotation results in raising the corner frequency
(shifting the curve to the right). To set the UF
rheostat:
1. Adjust the UF Rheostat fully CCW.
2. Start the generator and set at rated voltage.
3. Adjust the generator frequency to the
desired kneepoint frequency.
4. Slowly adjust the
clockwise (CW) until the generator voltage
just begins to decrease.
