MX321-2 AVR Stamford E000-23212/1P
The MX321-2 automatic voltage regulator is used on larger Stamford generator alternator ends. These units are installed as a standard from factory on alternator ends HC6 and P7 stamford frames. This regulator allows 3 phase sensing which is constantly sensing the voltages across all 3 lines vs just 2 lines like on other standard AVRs. As an added benefit the regulator enables quadrature droop input, this enables the chance for multiple synchronizing across many generator sets.
