Perhaps one of the most commonly used AVR’s in the Stamford line. Known by many techs, electricians, engineers and end users, the SX460 voltage regulator is a superior regulator with easy to use settings and very low price. Ā It’s ability to regulate voltage is essential with today’s power demand.
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.
