Description
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.
Compatibility:
Use with Power Factor Regular model M50FA400A. For varicomp model M40FA630A and M40FA632A.
Can be used on Marelli MJB 315 to 800 Generator frames.
