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 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 MA330 is used on large AVK generator ends. Although this regulator has already been discontinued the demand for this product is still very high. This AVR is still available for sale as a spare aftersales part. The new replacement is the new DM110 digital automatic voltage regulator.
