R230 AVR For Leroy Somer Alternators
Product Description
R230 is a Shunt excitation AVR for low voltage LEROY SOMER LSA 42.2, LSA 43.2, LSA44.2, LSA46.2, LSA47.2 three phase brushless alternators.

The regulator monitors the exciter excitation current as a function of the alternator output voltage. Very simple in design, the alternator with shunt excitation has no sustaining short-circuit capacity.
