R250 AVR controls the excitation current according to the alternator's output voltage.
With a very simple conception, the shunt excitation alternator is auto excited with a R250 and
excitation alternator does not have a short circuit capacity, voltage regulation: around ±0.5%.

1.Automatic Voltage Regulator R250
2. Suits leroy somer brushless alternator
3.Analogic Automatic Voltage Regulator with transistor
4.Applications Alternators LSA 42.2, 43.2, 44.2, 46.2, 47.2. Compatible with the SHUNT excitation syste.
