More Information

Overview Manuals Voltage Sensing Excitation Path Protective Logic Applications

Features:

  • Closed-loop excitation control maintains the selected synchronous-generator voltage.
  • The A1 option is configured for 100/120 VAC sensing at 50 or 60 Hz.
  • Shunt or PMG power can be supplied through single- or three-phase connections.
AVC63-12A1 forms its control error by comparing the rectified sensing signal with an internal reference.

Its power stage then varies DC field energy rather than switching the generator load circuit directly.

Droop, accessory-input, and protection functions allow the regulator to operate as part of a coordinated excitation system.

Apter Power supports documentation, selection review, and system matching for the Basler Electric AVC63-12A1 Voltage Regulator.

Measurement Configuration

  • A1 selection: The sensing circuit is matched to 100 or 120 VAC at 50 or 60 Hz.
  • Phase choice: Jumper positions select single-phase or three-phase voltage sensing.
  • Input burden: Each sensing phase draws less than 1 VA from the generator measurement circuit.
  • Trim range: The voltage-adjust control permits approximately ±10% adjustment from the nominal setting.

Field-Power Control

  • Power source: Excitation energy may come from generator shunt terminals or a permanent-magnet generator.
  • Continuous level: The regulated field output reaches 63 VDC at 12 ADC continuously.
  • Forcing duty: A ten-second ceiling of 125 VDC at 24 ADC supports transient excitation demand.
  • Field boundary: The connected field circuit must present at least 5.25 ohms of resistance.

Excitation Safeguards

  • V/Hz limiting: Selectable compensation lowers the voltage command as frequency falls below the knee.
  • Overexcitation trip: An inverse-time function shuts down output after excessive field demand persists.
  • Voltage buildup: Residual generator voltage initiates automatic excitation buildup.
  • EMI filtering: Internal suppression supports immunity to radiated, conducted, ESD, and fast-transient disturbances.

Generator Control Roles

  • Brushless excitation: The regulator controls the field of a conventional brushless synchronous generator.
  • Parallel operation: Droop compensation enables reactive-load sharing between generator sets.
  • Power-factor control: The accessory input accepts commands from a compatible var or power-factor controller.
  • Excitation limiting: An external limiter can bias the regulator through the same accessory interface.
Description
Basler Electric AVC63-12A1 is a generator automatic voltage regulator that senses AC output, converts the measurement to a DC control signal, and compares it with an internal reference.

Through its controlled field-power stage, Basler Electric AVC63-12A1 adjusts excitation to hold a brushless synchronous generator at the selected output voltage. The A1 configuration is intended for 100/120 VAC sensing at 50 or 60 Hz.

Basler Electric AVC63-12A1 accepts single- or three-phase shunt power or a permanent-magnet-generator source. Droop compensation supports parallel generator operation, and the accessory input accepts compatible var/power-factor controllers or excitation limiters.

Protective functions built into Basler Electric AVC63-12A1 include selectable volts-per-hertz compensation, inverse-time overexcitation shutdown, voltage buildup circuitry, and electromagnetic-interference filtering.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
How does AVC63-12A1 regulate generator output?
AVC63-12A1 converts the sensed generator voltage to a DC signal, compares it with a reference, and varies field power to correct the error.
What does the A1 suffix specify for AVC63-12A1?
For AVC63-12A1, the A1 option identifies 100/120 VAC sensing with a nominal frequency of 50 or 60 Hz.
May AVC63-12A1 use a permanent-magnet-generator source?
AVC63-12A1 accepts either shunt power or PMG power in a supported single- or three-phase connection.
Which external controllers can work with AVC63-12A1?
The ±3 VDC accessory input on AVC63-12A1 accommodates compatible var/power-factor controllers and excitation limiters.
Why is droop compensation provided on AVC63-12A1?
AVC63-12A1 uses an external current-transformer signal to establish droop for reactive-load sharing between parallel generators.
What occurs during overexcitation on AVC63-12A1?
AVC63-12A1 applies an inverse-time characteristic and removes regulator output when excessive excitation persists beyond the defined curve.
How does AVC63-12A1 respond to falling generator frequency?
Selectable V/Hz compensation lets AVC63-12A1 reduce the voltage reference below its knee frequency to limit generator over-fluxing.
