Product Description

STAMFORD AS480 is Stamford’s newest regulator and available on all P044 and P144 industrial and marine applications. The regulator can produce current forcing when installed with an EBS (Excitation Boost System) which has the same characteristics has a PMG (Permanent Magnet Generator), less expensive and no need to update the AVR. Unlike the SX460 the AS480 is equipped with a overexcitation shutdown in other words the AVR is constantly monitoring the exciter field and will provide the required signal to collapse the output voltage if needed. As a standard this regulator is only available in UL
