Basler AVC63-12A1 – Analog Automatic Voltage Regulator (AVR)

The Basler AVC63-12A1 is a rugged, high-performance analog automatic voltage regulator designed for brushless synchronous generators with a 63 V DC exciter field output. Built to deliver extremely tight regulation, reliable build-up from low residual voltages, and full paralleling/droop compensation capability, the AVC63-12A1 is ideal for industrial generator sets where stable voltage output, fast transient response, and low maintenance are critical.

Key Specifications
