GENERAL
ASR (Analogic Simplified Regulator)Ā is a closed loop regulator system that controls and keeps the voltage at a constant output.Ā The AVR is set with factory settings and it needs adjusting in order to meet your diesel generator specification

The Stamford Newage SX421 is used in critical power generation applications where load is unstable and a superior AVR is needed. Much similar to Stamford’s MX321Ā voltage regulator, the SX421 supports a larger resistance to heat exposure due to its high rated encapsulated material thatĀ prevent the automatic voltage regulator’s internal components from heat. Ā You have the option to use in 50 or 60 hz operation from below 40kw to above 550 kw generator sets.
The MX342-2 AVR is a key model which resembles a lot of the same functions of the MX341-2 however, this model contains a switch which allows you to choose which power rating (KW) you are currently using the regulator in and will adjust accordingly. Ā Some additional AVRĀ calibrations may be needed. Ā When presented to industrial experts for technical evaluations they advised that there should be a way to control stator current. Stamford went ahead and added a current limit feature which helps the engine recover from starting large compressors and motors.
This regulator needs to be used with a permanent magnet generator (PMG)
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.
