Features:
- AVC63-12A1 style code selects 63 Vdc at 12 Adc output, 100/120 Vac sensing and 50/60 Hz.
- Single- or three-phase sensing and shunt or PMG power input are supported within the documented limits.
- Frequency compensation, overexcitation shutdown, droop compensation and accessory bias input are integrated.
AVC63-12A1 senses generator terminal voltage and controls dc field power to maintain the voltage setpoint. The regulator includes selectable underfrequency compensation, inverse-time overexcitation shutdown, voltage buildup circuitry and parallel-droop compensation.
Before removal, record every terminal connection, jumper, adjustment position, sensing transformer, CT polarity, field resistance, excitation source and generator operating data. After installation, complete the approved static checks and generator commissioning procedure before applying normal load.
The AVC63-12A1 BASLER ELECTRIC Automatic Voltage Regulator is listed as Active / Available from OEM. Current revision, availability and supplied scope are confirmed in the written quotation.

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
AVC63-12 identifies 63 Vdc at 12 Adc maximum continuous output. Style A selects nominal 100/120 Vac sensing and style 1 selects 50/60 Hz operation.
Confirm 90 to 153 Vac power input, 90 to 139 Vac sensing, field resistance, phase configuration and the exact shunt or PMG excitation source before wiring.
The regulator supports single- or three-phase sensing and 1 or 5 A CT secondary input for droop or line-drop compensation. CT polarity and sensing-transformer grounding must follow the approved generator design.
Record underfrequency, droop, voltage and stability settings before removal. Do not alter the factory-calibration control unless the manufacturer procedure specifically requires recalibration.
Match every numbered terminal, F1 and F2 field polarity, phase arrangement, grounding and protective device. Confirm the generator is stopped and isolated before any field-flashing or wiring work.
Commission with the approved generator procedure: verify voltage buildup, sensing, field output, underfrequency response, stability and regulation under controlled no-load and load conditions.
