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%.

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.
