R250

R250 is an analog AVR with power controled by transistors. It is designed for small alternators with a SHUNT excitation. R250 controls the excitation current in order to maintain the output voltage of the alternator. R250 is performant in terms of voltage regulation, simple to set, to use and is reliable.
