MX341 AVRThis sophisticated AVR is incorporated into the Stamford Permanent Magnet Generator (PMG) control system . The PMG provides power via the AVR to the main exciter, giving a source of constant excitation power independent of generator output . The main exciter output is then fed to the main rotor, through a full wave bridge, protected by a surge suppressor . The AVR has in-built protection against sustained over-excitation, caused by internal or external faults . This de-excites the machine after a minimum of 5 seconds . An engine relief load acceptance feature can enable full load to be applied to the generator in a single step . If three-phase sensing is required with the PMG system the MX321 AVR must be used.We recommend three-phase sensing for applications with greatly unbalanced or highly non-linear loads.
