ADVR440

Hybrid Analog/Digital Single Phase sensing 4 Amp Automatic Voltage Regulator for self-excited (shunt) generators

ADVR-440 is a direct replacement for Newage Stamford AS440 and also compatible with SX440. It’s equipped with Quadrature Droop Input for parallel operation, Over Excitation Protection, Soft Start Voltage Ramping Function, Digital Voltage Sensing and Under Frequency Protection Circuit which effectively reduces the thermal drift.
