The MX321 ^TM analogue, 3-phase sensing, permanent magnet generator (PMG) powered automatic voltage regulator (AVR) provides isolation from the effects of non-linear loads, improved motor starting performance and sustained short circuit current.

The MX321 ^TM AVR is provided as standard for the STAMFORD ^® S6 and HC6 alternators and can also be provided as an option across the STAMFORD ^® range
