Generator parts Automatic Voltage Regulator circuit diagram Three Phase Automatic Voltage Regulator power avr MX341

Product Description

MX341 Permanent Magnet Generator type voltage regulator is a compatible replacement for NS MX341 and Onan 305-0846.

MX341 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-phase permanent magnet generator(PMG), to isolate the AVR.control circuits from the effects of nonlinear loads and to reduce radio frequency inference on the generator terminals. Sustained generator short circuit current is another feature of the PMG system.

The AVR senses the voltage in the main generator winding and controls 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 RMS sensing is employed for superior voltage regulation.

Adjustable soft-start circuitry is included to provide a smooth controlled build-up of the generator output voltage.
