Stamford AS440 Automatic Voltage Regulator (AVR)

Description

Advanced Analog Voltage Control

The AS440 is a self-excited AVR that provides high-performance voltage regulation for brushless generators. It uses a half-wave phase-controlled thyristor output to maintain a constant output voltage regardless of load changes. The module is designed for reliability in demanding environments and is fully compatible with the Stamford HC544 and many other large industrial alternators. It includes frequency-sensitive protection circuits and an optional linkage for droop operation when running generators in parallel. Its analog design ensures fast response times and stable operation for sensitive electrical loads.
