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.Leroy Somer Automatic Voltage Regulator R2502. Suits leroy somer brushless alternator3.Analogic
Automatic Voltage Regulator with transistor4.Applications Alternators LSA 42.2, 43.2, 44.2, 46.2, 47.2. Compatible with the SHUNT
excitation system. The R250 is in Compliance with: IEC, VDE, NEMA, BS, CSA, UL508 CE low voltage.
