The M31FA600A MEC-20 voltage regulator is suitable for synchronous generators constructed by MARELLI MOTORI from series MJB for sizes 315 to 800.
The M31FA600A voltage regulator is a micro-processor device with pulse-width modulation (PWM) output stage, and can be calibrated using potentiometers. The circuit board is resin-bonded in order to maintain a high degree of operational reliability even in difficult environmental conditions (high levels of humidity, dust, a salty atmosphere) and in the presence of vibrations.
Use with Power Factor Regular model M50FA400A. For varicomp model M40FA630A and M40FA632A.
Can be used on Marelli MJB 315 to 800 Generator frames.
