AVR AS440 | Original

The AS440 Automatic Voltage Regulator (AVR) is a half-wave, phase-controlled thyristor regulator that forms a critical part of the excitation system in brushless generators. This model, supplied as a kit replacement for the SX440 and SA465, actively regulates generator output voltage to ensure stable and reliable performance.

In addition, the AS440 AVR integrates underspeed and sensing-loss protection, helping protect the generator and excitation system during abnormal operating conditions. These built-in safeguards ensure safe, dependable voltage control across a wide range of generator applications.
