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. 2.1 - Characteristics - Voltage regulation: around ± 0.5%. - Voltage supply/sensing range 85 to 139 V (50/60 Hz) - Rapid response time (500 ms) for a transient voltage variation amplitude of ± 20% - Voltage setting P1 - Stability setting P2 . - Power supply protected by 8 A fuse, slow-blow action (tolerates 10 A for 10 s) - Frequency: 50 Hz with ST3 jumper - 60 Hz without ST3 jumper - Factory-set underspeed protection P3 . 2.2 - R230 AVR option Potentiometer for remote voltage adjustment, 1000 Ohms / 0.5 W min: adjustment range ± 5%. - Remove the ST4 jumper. Initial potentiometer settings - P1potentiometer (AVR voltage adjustment): fully anti-clockwise. - Remote voltage adjustment potentiometer: centre position. Run the alternator at its rated speed. If the voltage does not increase, the magnetic circuit should be remagnetized (see section 2.3). - Turn the AVR voltage adjustment potentiometer P1slowly until the output voltage rated value is obtained. - Adjust the stability setting using P2. - Sealed potentiometer P3 is factory set at 48 Hz for 50 Hz and 58 Hz for 60 Hz
