The M31FA600A is a digital automatic voltage regulator made by Marelli in Italy. Works with Auxiliary winding or PMG. This regulator senses all 3 phases and adjusts excitation accordingly. AVR protection is key that is why Marelli made sure to include an under-Frequency and over excitation limiter, very crucial in all power generation applications.
