MX341-2 regulator is one of the 2 “MX” series used in the Stamford line of automatic voltage regulators. Ā Cummins Stamford has depended on this AVR board over the years to assist in critical applications where voltage regulation and stability is key.
This regulator needs to be used with a permanent magnet generator (PMG)
The DM110 is CGT’s newest automatic voltage regulator brandedĀ AVK/Stamford. Ā It is a digital type regulator which allows very accurate voltage regulations on generator alternator ends. This regulator is programmable via computer and has very easy setup and is very easy to use.
The MX321-2 automatic voltage regulator is used on larger Stamford generator alternator ends. Ā 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.
