Blue Capacitor AVR MX321 for Brushless Generator /Diesel Generator
Set Automatic Voltage Regulator
* 3 Phase Sensing Permanent Magnet Generator type voltage regulator
is a compatible replacement for Newage MX321 and Onan 305-0823.
* MX321 is a three-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
interference 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.
