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 MX321 voltage regulator, the SX421 supports a larger resistance to heat exposure due to its high rated encapsulated material that prevent the automatic voltage regulator’s internal components from heat. You have the option to use in 50 or 60 hz operation from below 40kw to above 550 kw generator sets.
