Stamford AVR MX321
*3 Phase Sensing Permanent Magnet Generator type voltage regulator
is a compatible replacement for Newage Stamford MX321 and Onan
*MX321 is a 3 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 magnet
generator(PMG),to isolate the AVR control circuits from the effects
of nonlinear loads and to reguce radio frequency interence on the
generator terminals.Sustained generator short circuit current is
another feature of the PMG system.
