Description:
Leroy somer 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 R250 2. Suits leroy somer
brushless alternator 3.Analogic Automatic Voltage Regulator with
transistor
4.Appliions 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.
