AS480UL AVR Stamford E000-14808/1P


Special Price $274.00

The Stamford AS480UL AVR is one of the newest automatic voltage regulators introduced as a standard on all P0/P1 Stamford frames. This voltage regulator uses the same functions as a standard Stamford regulator but is made specifically to work with an Excitation Boost System (EBS) to provide a short-circuit current when needed. Unlike other regulators in the market this AVR in particular is UL rated and can be used in a UL2200 application.

AS440 AVR Stamford E000-24403/1P


Special Price $519.00

Stamford’s AS440 regulator is utilized in brushless alternators providing regulation and stability in an automatic fashion. This AVR supports droop inputs for synchronizing on 2 or more AC alternator/generators.  Along with the added features the AS440 has an option for a hand trimmer, this is best used in applications where a voltage selector switch is present.

MX342-2 AVR Stamford E000-23422


Special Price $472.00

 

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.  Some additional AVR calibrations may be needed.  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.

MX321-2 AVR Stamford E000-23212/1P


Special Price $698.00

The MX321-2 automatic voltage regulator is used on larger Stamford generator alternator ends.  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.

SX421 AVR Stamford E000-24210/1P

Retail Price

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.
