Avr Sx440 Module Automatic Voltage Regulator For Newage Stamford Generator Dho

Avr Sx440 Module Automatic Voltage Regulator For
The AVR has the faclity for droop CT connection,to allow parallel running with other similarly equipped generators.
SX440 is a two phase sensed Automatic Voltage Regulator(AVR) and forms part of the exciation system for a brush-less generator.
The AVR senses the voltage in the main generator winding and control the power fed to the exciter stator and hance the main rotor to maintain the generator output voltage within the specified limits, compensating for load sprrd,temperature and power factor of the generator.
