Automatic Voltage Regulator AVR Module 305-0846 for Cummins Onan Stamford Newage
This AVR is a two phase sensed Automatic Voltage Regulator and forms piece of the excitation structure for a bursh-less generator.Excitation control is derived from a three-phase permanent magnet generator (PMG),to isolate the AVR power circuits from the effects of nonlinear loads and to reduce radio frequency interference on the generator terminals.Constant generator short circuit current is another feature of the PMG system.
The AVR senses the voltage in the central generator winding and controls the power fed to the exciter stator and hence the main rotor to keep the genertor output voltage within the specified limits,compensating for load,speed,temperature and power factor of the generator.
Soft start circuitry is included to provide a even controlled build up of generator output voltage.
