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 butĀ is made specificallyĀ 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.
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. Ā 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.
