The STAMFORD® AS480 Automatic Voltage Regulator (AVR) is Excitation Boost System (EBS) compatible for short-circuit current maintenance, a feature the AS440 does not support. It is used on all P044 and P144 industrial and marine applications. The AS480 has an over-excitation (AVR EXC) control, which will constantly monitor for excitation voltage exceeding a set threshold to help keep the alternator safe.
Power input voltage is 100-264V ac 1 phase and Frequency 50-60 Hz nominal. Power output voltage is 82V dc @ 200V ac.
