Product Description

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. 
The R250 is in Compliance with: IEC, VDE, NEMA, BS,  UL508 CE low voltage.
