Features: MX341A is 2 phase sensed automatic voltage regulator and forms part of the excitation system for a brushless generator. Excitation power is derived from a three phased permanent magnets generator, to isolate the AVR, control circuits from the effects of nonlinear loads and to reduce radio frequency interence on the generator terminals. Sustained generator short circuit current is another feature of the permanent magnets generator systems. The AVR sense the voltage in the main generator winding and control the excitation to maintain the generator output voltage with the specified limits, compensating for load, speed, temperature and power factor of the generator. Thress phase sensing is emplyed for superior voltage regulation. Adjustable soft start circuitry is included to provide a smooth controlled build up of generator output voltage.
