Basler AEC63-7 Analog Excitation Controller

The Basler AEC63-7 is an analog excitation controller designed for synchronous generators operating across a wide frequency range of 50‑400 Hz. This controller provides automatic voltage regulation (AVR) for generator sets used in aircraft, military, and industrial applications where variable frequency is common. The AEC63-7 accepts an input voltage of 190‑277 V AC and delivers regulated excitation to maintain stable generator output voltage.

The controller features robust analog circuitry with adjustable voltage setpoint and stability controls. It includes protection against over-excitation and loss of sensing. The AEC63-7 is designed for panel mounting and is built with high-reliability components suitable for demanding environments.
