Mx341 Avr For Stamford Generator

This regulator fully replaces the original Stamford MX341 AVR for Stamford Generator. It is built to fully replace the original version, same fit, form and function.

MX341 is a two phase sensed Automatic Voltage Regulator and forms piece of the excitation structure for a
brush-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 generator 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.
