R250 LIXiSE 3 phase avr for generator voltage regulator

Product 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.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.
