Regulators have seen many design improvements over the decades, but the most commonly used electro- mechanical regulator is the three-control units in one box type. Mechanical Voltage Regulator Characteristics – Power Quality vs Line Drop. Mechanical voltage regulators for power quality and utility line drop compensation (LDC) function in similar manners but they differ substantially in application: . It can be used in vintage cars, motorcycles, trucks, tractors and boats. Replace your old mechanical regulator with an all-electronic regulator that never requires cleaning .

Essentially, the relay(s) employed .
Even the old points type mechanical regulators could open and close the points over 2times per second!
Electronic voltage regulators have replaced the old . So hopefully this article has explained in simple terms how the sometimes rather confusing Lucas electro- mechanical voltage regulator unit works. It is based upon the Lucas MCRunit fitted to my bike, but is the same for the earlier Lucas MCRunits and also for the Later RB1Control .
